GRUNDIG 4010W

Grundig 4010W生产于19521953年,4010W属于GRUNDIG的高质量机型之一,当然整机是德国制造。

古老的收音机柜

让我们从机柜描述开始。
机柜尺寸显然很重要。该收音机不能被视而不见。木材纹理是美丽而明显。
机柜经过进一步的改进而变得更加丰富,线条清晰,两侧细致,前面板不是简易的画上线条,而是正宗的木条镶嵌。
今天,无论是成本还是精致程度,这样的做工是难以置信的。

40101W短波的频段分为三段:

SW1 -  50,8 to 35 mt (5,9 - 8,6 MHz)
SW2 - 35 to 24 mt (8,6 - 12,5 MHz)
SW3 - 24 to 16,7 mt (12,5 - 18 MHz)

这種波段上的调谐可以非常精确。
在往後的几年里,短波波段通常被压缩成一段式。

中波也分为兩段:

MW1 - 585 to 318 mt (515 - 945 kHz)
MW2 - 321 to 185 mt (935 - 1620 kHz)

此外,内置了一个中波选台的记忆装置。按下ORTS-S按钮,旋转和调整到一个最喜欢的电台。

FM波段范围从87.5100 MHz。我们强力推荐这台收音机安装蓝牙接收器。

放大器的部分包括一个经典的EABC80放大管作为前置放大器,用来控制高低音。输出级是一个强大EL12A级放大管。
它提供了一个负反馈系统,细致反映线性响应的输出级频率。
因为电路没有引入高反馈因数,所以声音仍然很自然。

输出变压器的尺寸很好,所以不可能产生饱和效应。

所有这些昂贵的技术解决方案的结果,使高品质的声音重現。
这是一个极緻的GRUNDIG作品。

音调控制

音调控制系统是非常有效的,在音调控制大旋钮上,你可以找到一个小窗口,黑白颜色对比逐渐显示出对高低音比例。

有趣的高音控制旋钮连接到两条细绳。其中之一是用于控制本身的位置指示器,而另一条用于改变MF变压器中的铁素体的位置,改变变压器曲线的倾角。

这样一来,即使在进入BF阶段之前,高音调也会减弱/加重。功率放大器级通常采用电位器控制音调。

天线

机柜内有一个FM调频接收偶极。
偶极的一端也用于接收AM波段
具有内部天线的接收灵敏度很好。
使用外部天线灵敏度进一步增加

调谐控制

无论调幅AM和调频FM波段,调谐系统是非常独特的。
单一可变电容被分为4个部分,两个调幅AM和两个调频FM
每个部分分别用于射频放大器和振荡器。
该机制非常简单和坚实。它的缺点是所有波段的唯一控制。

调谐指示器

调谐指示当然已经被更换

频带指示器

配备这种漂亮的按键,叫做“钢琴”,你就不知道哪个键被按下了,哪个波段正被收听了。
由于这个原因,每个按钮都有一个指示器,按下相对键时颜色随之改变。

扬声器

有两个喇叭。
这对扩音器非常大。
事实上,这也是用于5010机型相同的组合,5010机型配备两支EL12推挽放大管。
这算是一个大型收音机。
Grundig原厂生产的扬声器。
一个非常有趣的特点是,他们配备了一个可调裝置。
这允许我把圆锥体的运动集中在磁系统上。
中高音有一个超大的磁铁。它必须忍受相当大的功率峰值,因为它被切割得非常低。
声音清澈且甜美。
扬声器经过纤维素处理的,到今天为止完好无损,没有任何变形或结构破坏。他们“至少”必须持续原创期时建造的样貌。

GRUNDIG 3012

The Grundig 3012 is a very special device called friendly "The bufferfly" because the loudspeakers position. The classification of Grundig devices is as follows:

Serie 1 xxx – Economic Class (ie.1060)
Serie 2 xxx – Economic - Medium Class (ie.2035)
Serie 3 xxx – Average Class (ie.3012)
Serie 4 xxx – Medium – High Class (ie.4035)
Serie 5 xxx - High Class (ie.5010)
Serie 6 xxx – Very High Class (ie.6099)

The Grundig 3012 belongs to the Medium Class but it has some features of the Upper Class.
Firstly, the final tube is a powerful EL12, normally used on Serie 5 devices.

The EL12 is a large pentode that delivers until 8W in A- Class.
The output transformer is a very large, almost like the power transformers in a normal radio, so it hardly goes into saturation.

Another important feature is the two elliptical loudspeakers.
Together, they can reproduce very low notes. Being smaller, they are faster and for this reason the bass is very limited, pleasant and modern.

Finally, the central tweeter and the symmetrical arrangement of the two broadband loudspeakers simulate a sound emitting point source. In this way, it is possible to get a remarkable “soundstage” effect and great depth of environment.

The cabinet of the radio is very beautiful and contains a surprise.
The clear frames that you can see on the sides are not painted, but they are inlaid.
All of these architectural choices do not belong to a Medium Class device, in fact Grundig 3012 is not a device of that class.

TONE CONTROL WITH LEVEL INDICATION

The tones control system is very efficient. Above the large tone control knobs there is a band that lights up gradually indicating the emphasis on the band on which it acts.
Interesting the high-tone control knob linked to two thin ropes. One of them is for the position indicator of the control itself, whereas the other changes the position of the ferrite in the MF transformers modifying the inclination of the transformer’s curve.
By doing so high tones were attenuated/accentuated even before getting to the BF stage. Tone control was usually put into effect with the potentiometer on the voltage amplifier stage

AERIALS

Inside the cabinet there is a dipole for FM reception.
One arm of the dipole is also used for receiving AM bands.
Listening FM band the reception sensitivity with internal aerials is very good.
For AM bands using an external antenna the sensitivity is good.
The picture shows the dipole fixed internally to the cabinet.

Grundig 3012

TUNING CONTROL

For both AM and FM bands the tuning system is unique.
The single variable capacitor is divided into 4 sections, two for AM and two for FM.
Each section is used respectively for the RF amplifier and the oscillator.
The mechanism is very simple and robust. It has the disadvantage of being a unique command for all bands.

TUNING INDICATOR

The magic eye has of course been replaced.

Grundig 3012

LOUDSPEAKERS

There are three speakers, but what matters most about this unit is their arrangement.
They are arranged to reproduce the sound as if it came from a point source, like in a single speaker.
The acoustic result is extremely enjoyable, and the rebuilding of the scene is realistic. You find the depth and the space.
The bass is very deep and fast, and the acute are balanced, thanks to the help of the central electrostatic tweeter.
I do not understand why this configuration was not re-proposed even in the most expensive models. Maybe just to keep costs down.

CONTROL PANEL

Grundig 3012

Starting from the left, there are two coaxial knobs.
The most exterior and smaller, is that of the volume.
The internal knob, the larger one, is the control of acute tones.
Above this knob, the larger one, is the control of acute tones, and a little window is visible indicating its position.

We also find the power off buttons, which input from the record player, FM, Short Medium and Long Waves.
There are also two coaxial knobs. The most exterior and smallest, is the tuning knob.
The internal and largest, is the low tone control knob.
Above this, a little window is visible indicating its position.

GRUNDIG STEREOMEISTER 300

The following model, the Stereomeister 300 has a transistor FM converter, whereas in the immediately following models the FM valve converter stage has been reinserted.
This device is therefore remarkable both for its wonderful aesthetics designed by Grundig in those years and for the extremely modern features only to be found in later models.

The final stage is a class AB Push-Pull with a feedback circuit for response linearization and distortion decrease.
The response is indeed generally balanced and with a powerful push on bass regardless its small output transformers.
By employing efficient diffusers the power is more than appropriate even if you want to play the in big spaces.

I personally recommed to play this device at 3/5 of its maximum volume.
The response curve changes according to the position of the potentiometer that controls and corrects the volume.
The shift from the section with volume correction to the one with no correction is fairly audible, that is the reason why it is preferable to maintain the volume under the said limit.
No need to say that if you want to take full advantage of the power of this device ... you can turn the volume knob as much as you want.

Following Grundig’s tradition, the radio section is extremely stable, sensitive and free from ground noises.
Even the final stage is silent and buzzless.

Sound high quality, the stereo decoder and the absence of inner loudspeaker (giving the device a rather modern shape) make of this device a great collector’s piece.

After the Stereomeister series Grundig as well as other big german brands started to save on and “optimize” their projects and unfortunately their quality began to decrease and “more modern” quality criteria started to take over.

This device is one of the rare and few Grundig Hi-Fi tube stereophonic receivers

SEPARATE LOUDSPEAKERS

The original loudspeakers, that can be buyes separately, are composed each one of a double Mid-Woofer loudspeaker and coaxial tweeters. They create a not that brilliant yet balanced sound.
The Stereomeister has 7,5 + 7,5 W output in ultralinear configuration but it can drive big loudspeakers without problems.
In the main gallery you can see the Stereomeister with a couple if AR 98 LS-U.

STEREO DECODER

The radio is equipped with a tube Stereo-Decoder, that means it is a real stereo, not like most other vintage radio that used to be mono in the radio FM and stereo sections only because of the double final section.
To be clear, on the other radios the record player could be played in stereo, but the radio only in mono.

The unit is equipped with mechanisms for keeping separate the AM bands by each of the other two FM bands.
The tuning knob is single but a selector switch commutes into cable systems (all in steel) and pulleys separated depending on the band.

GRUNDIG STEREOMEISTER 15

Despite the look futuristic, for that time, the Stereomeister 15 use only tube circuits.
In this device the original decoder has been replaced with a modern decoder specifically designed. This decoder has a better separation and a lower noise rate than the original one.

The most interesting feature of this model is that the output transformers are bigger than in later models.
I think that also the German industry progressively saved money in their projects.
Transformers larger means less possibility of saturation, deeper bass and lower distortion.
Like others Stereomeister the final stage is a class AB Push-Pull with a feedback circuit for response linearization and distortion decrease.
By employing efficient diffusers the power is more than appropriate even if you want to play the in big spaces.

The response curve changes according to the position of the potentiometer that controls and corrects the volume.
The shift from the section with volume correction to the one with no correction is fairly audible, that is the reason why it is preferable to maintain the volume at a certain level.

The unit is equipped with variable control of the Hall effect.
This refinement has been implemented in order to obtain a depth similar to what you have listening music in a very large room, such as a cathedral.
It's achieved by delaying the sound than the original and remix both.
I discourages the use of the Hall feature. The effect can be pleasant but it is a distortion of the original informations.

Following Grundig’s tradition, the radio section is extremely stable, sensitive and free from ground noises.
Even the final stage is silent and buzzless.

Sound high quality, the stereo decoder and the absence of inner loudspeaker (giving the device a rather modern shape) make of this device a great collector’s piece.

Produced in 1964 the Stereomeister 15 belongs to the Grundig highest class tube radio.

GRUNDIG 4085

As for the Grundig 4095 I would like to tell a brief history this cabinet design.
Manufactured in 1956, the 4085 radio set was a Grundig mid-high grade equipment. What distinguished it from other high class Grundig radios was its special design shaped like a stylized Lyre.

Grundig 4085To Greek mythology, the inventor of the lyre was Hermes, who built it with a tortoise shell and a sheep gut to donate it to Apollo, who then gave it as a gift to his son Orpheus. In classical era, the lyre was linked to Dionysus and represented ecstasy and celebration. The lyre probably originates from northeastern Africa.
The design was used in some rare devices previous very daring.Grundig 4085
An interesting example is the Tonfunk (in fact subsequently absorbed by Grundig) Violetta Lyra 1955, visible in the image on the right.

In my opinion the 4085 and 4095 are the big capacity of synthesis of Grundig designers.
They design evoke the sinuous forms of Lira while maintaining clean lines, which they did at the time, growing old hit most other radios on the market.

 

Some stylistic solutions typical of this model were then adopted also by many other manufacturers for a long time.
For instance, the wooden frontal fillets designed to protect the speakers will be used in appliances and speakers until the '70s.
Even the golden color of the cabinet along with the four-sided and sharp lines will denote the most of the forthcoming production as a leitmotif.

Produced in 1956/57, the Grundig 4085 was the upper-mid range device with the most innovative look ever created by this brand.
In that same period, Grundig produced another line, the 4095, which was slightly larger and had a push-pull output stage.
The two devices, however similar, had unique defining characteristics and uses. One is not better than the other as each device has it's own key feature.
The 4095 was privileged with greater power and is better adapted to filling larger environments with sound.
The 4085 was given a Class A output stage, it has a more refined and warmer sound even if it is less powerful.
The EL84 is considered to be one of the best musical tubes ever produced. In fact, it is still used today in high-end amplifiers.
The tone controls are inserted into the feedback circuit so that distortions are further reduced.
Alnico wide-band loudspeakers are very efficient, requiring little power to reach elevated levels of sound pressure.
Furthermore, the warmth of this sound is that typical of very fast wide-band loudspeakers
Today, this type of wide-band loudspeaker is increasingly used in the production of high efficiency horn loudspeakers.
Another musical device with an incredibly modern look.

GRUNDIG 4040W/3D

At first glance this Grundig looks like a regular high class device of the prestigious german brand. It is not like that.

3D

At that time Grundig was producing its three high class models: the 4040, the5040 and the 5050.
These devices were produced both in 3D with side loudspeakers and only with front loudspeakers.
Compared to front loudspeaker radios, 3D models are endowed with a strong depth effect as far as the sound image is concerned.

Motorized tuning

The three 3D system high class models were also equipped with a motorized tuning system.
It is clearly possible to manually tune the stations by employing the switch to exclude the motor.
The tuning mechanism is an authentic masterwork and it will be described as follows.
The video file (37,31 Mb), which can be downloaded, best shows the functioning of the 4040W/3D.

In those years Grundig began to intensely export its products to the USA. The demand got to such a high level that the joint-venture with the American brand Majestic was created.
Technical specifications of these devices were even stricter than those produced for the inner and the European market.
Grundig decided to produce devices that were suitable for European broadcasting systems while employing Majestic’s restrictive specifications. This 4040W/3D model is one of those rare Grundig/Majestic appliances

It is equipped with a double output transformer for low and medium-high frequencies.
Regular 4040W/3D used to be equipped with a single output transformer. The 4040W/3D has the powerful (18W) EL12 as its power tube.

Other than the electrostatic tweeter, the 4040W/3D has a huge elliptical multioctave woofer with a die-cast drum, which ensures a deep and sweet bass even with the central bass potentiometer (which I suggest).

Watching the big needle going through the scale of its own accord is extremely fascinating.
Due to its design and the robust piece of furniture, which works as a real loudspeaker, the sound of this device is extremely warm and well-rounded.
Further information about the extraordinary refinement of this device will be listed down below. A real delight both to be listened in on and to be seen.
Furthermore, its rareness makes of it a real collector’s item.

One of the greatest expressions of german technical refinement in 1954,
Her Majesty the Grundig-Majestic 4040W/3D.

Rotating ferrite antenna for AM

Grundig 4040W/3D

TONE CONTROL WITH LEVEL INDICATION

The tones control system is very efficient. Above the large tone control knobs there is a band that lights up gradually indicating the emphasis on the band on which it acts.
A detail specific for “extreme” technical radios lovers: the high-tone control knob is linked to two thin ropes. One of them is for the position indicator of the control itself, whereas the other changes the position of the ferrite in the MF transformers modifying the inclination of the transformer’s curve.
By doing so high tones were attenuated/accentuated even before getting to the BF stage. Tone control was usually put into effect with the potentiometer on the tension amplifier stage.

AERIALS

Another refined feature: like other devices ( also lower class) the ferrite antenna is rotable and it can be activated through an external knob.
It places the antenna orthogonally in respect to the repeater so as to receive the highest signal. As far as this device is concerned the ferrite antenna is introduced through a switch, which is automatically switched on when the knob is turned. The latter is coaxial to the volume knob.

The position of the antenna can be read through the transparency of the magic eye. The resulting effect is amazing. When the antenna is disconnected you can read AUS on the magic eye.

Inside the case there is dipole for FM reception as well as an adjustable ferrite antenna for AM reception.

Remarkable is the perception of the reception with the inner antennas. The employment of an outer antenna ensure and unbelievably good perception. This device was indeed produced when there were a few and very far from each other radio stations.

TUNING SYSTEM

The tuning system is a real masterwork.
When the tuning switch is on AUS the tuning is manual as in regular devices.
When the automatic tuning switch is on EIN the current station is “mechanically” stored.

Example:
I pushed UKW2 and I am listening to a 89.90MHz station.
If I now push any of the other tuning buttons, the motor will take the pointer to the last listened station.
Pushing then UKW2 again the motor tunes exactly at 89.90 MHz.

The process can be repeated for any station on UKW1 UKW2 MW1 MW2 and LW bands.

The mechanical memorization is achieved through a number of frictions, springs, steel tie-rods and levers that require an accurate calibration.
Once calibrated and oiled, the mechanical system is extremely reliable and robust.
Its cogged wheels and flexible steel-blade frictions prevent any possible slid. A remarkable example of mechanical engineering.

TUNING INDICATOR

The tuning indicator has of course been replaced.

GRUNDIG 4035W/3D

Produced in 1954/55, the Grundig 4035W/3D substituted the glorious 4040W/3D.
It inherited the great sound created by the huge loudspeaker system and the Class A final stage.

The modern EL84 substituted the EL12 for a more precised and defined sound, if that is even possible. The EL84 is still considered one of the most musical tubes ever produced and it is still used in the High-End amplifiers.

Even in this case the device is equipped with a double output transformer and with an elaborate feedback system that has been designed to linearize the frequency response in the output stage.
The second output transformer is specific for the side loudspeaker so that you will not ever have saturation effects.
It is of course an expensive solution that will be abandoned in later production.
The tone controls are inserted in the feedback circuit so that the distorsioni is further reduced.

The FM converter stage is composed of two separate triodes as in the most prestigious SABAs.
This stage is amplified by an exclusive circuit equipped with an EF89 before continuing in Medium Frequency stage.
This peculiarity reduces the interferences, already very minimum, with the amplitude signal’s width fluctuations.
Tuning is therefore extremely stable.

All these expensive technical solutions create a high level sound quality. The 4035W/3D makes us incredibly satisfied.
