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.

TUBES

The tubes are ECC85 ECH81 EAF801 ECC83 EM87 ECC81 EC92 ECLL800 ECLL800.
The 2 ECLL800 are like of a Push Pull of 4 EL95 with their own preamplifier stages built inside.

AERIALS

Inside the cabinet there is a dipole for FM and a ferrite antenna for AM reception.
The receiving sensitivity with internal antennas is very good.

SEPARATE CONTROL TUNING BETWEEN AM AND FM

The tuning system is another gem.
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.

主要的控制

Grundig Stereomeister 300

Inside the black line ... we find the bass control under the magic eye (tuning indicator), the treble control and the volume control with loudness built-in and coaxially the balance control.
Continuing we find the record player button, the Mono/Stereo switch, LW, MW, SW and FM knobs.
On the right side the power switch.
The stereo indicator is on the left.
Under the magic eye that indicates the perfect tuning of each station.
To the right there is the AM main display for Long Wave Medium and Court bands, and the FM display.
Finally, there is the tuning knob.
The movement of the tuning knob is very pleasant being supported by a large flywheel.
