Le radio a valvole prodotte in Germania negli anni 50/60 sono famose in tutto il mondo per la loro eccellente sonorità, la bellezza delle loro finiture, la robustezza ed il loro standard di costruzione senza compromessi.
Purtroppo la banda FM di estende dai 87.5 ai 100 MHz per cui ricevono solo alcune stazioni.
Dopo attenti studi ed un gran numero di prove siamo stati in grado di allargare la banda ricevibile da 88 a 108 MHz.
Naturalmente abbiamo dovuto ricostruire anche la scala parlante, identica all'originale, fatta con gli stessi materiali e le stesse tecniche, ma con il nuovo intervallo di frequenza.
Il risultato è perfetto. Un apparecchio originale ma con la possibilità di ascoltare qualsiasi stazione in qualsiasi parte del mondo.

Qui sotto i modelli di radio con la banda FM allargata:

BLUETOOTH

Normalmente forniamo le nostre radio di un particolare cavo che permette di connetterle a qualsiasi dispositivo digitale (MP3 reader, CD player, iPad, Smartphone, etc.).
Su richiesta possiamo dotare tutti i nostri apparecchi di ricevitore Bluetooth.
Questo permette di comandare le nostre radio da qualsiasi sorgente Bluetooth; in sostanza da qualsiasi dispositivo multimediale.
Diventa così possibile ascoltare qualsiasi web radio, o qualsiasi playlist memorizzata in un media player, o computer, o smartphone.
Usando il microfono dello smartphone la radio dotata di Bluetooth diventa anche un dispositivo vivavoce.
Il Bluetooth ha una portata di circa 10 metri. Poichè i normali muri non sono considerati ostacoli, il dispositivo di controllo della radio può essere anche in un'altra stanza.
Il volume può essere controllato sia dalla radio che dall'unità Bluetooth sorgente. Va regolato il volume della radio al livello desiderato e poi lo si controlla dall'unità Bluetooth sorgente, come fosse un telecomando.
Naturalmente se il volume della radio è al minimo, il controllo da remoto non ha alcuna efficacia.
La procedura di peering è molto semplice, e va eseguita solo la prima volta che si connette un dispositivo sorgente.

LE VARIE FASI DI UN RESTAURO

Does it look brand new? Let’s see how we got to this result
Prior the restoration- it could be in these conditions after 60/70 years
Or be delivered like this if it traveled in an inadequate package
Or even worse if it was highly damaged during the shipping
THE WOODEN CABINET - its restoration might require the complete removal of varnish and original cladding
Original varnish removal implies the removal of any other type of upholstery and decorations that should be photographed and measured in order for them to be faithfully rebuilt
Here is the cabinet after the painting. The restoration technique employed on the cabinet will depend on its age and on the originally employed technique
KNOBS. You begins with a pivot identical to the one on the radio device. On the same device pivot might have different diameters and forms
Starting from an original knob you can build the molds and then you create the new knob with a mixture of the same color of the original knobs
DIALGLASS- with a software you can prepare a file and then you print out a film for each color (in the picture there are two colors, gold and black)
The negative films give gelatine to the structures in the dark and you let them dry in the oven
The structures, incised with a gush of water, are dried and are ready for the serigraphic projection on glass
Layers of paint are spread and it goes through the non-clogged holes of the structure
In order to get to a dialglass which is completely undistinguishable from the original
LOUDSPEAKER PANEL - the front canvas is dry cleaned by a specialized dry cleaner
Sometimes restoring the weave needs to be restored with original yarn
ELECTRONIC - the cleaning phase is very important for the mechanical and electronic restoration. In the picture only half of the device has been cleaned
Here is what a cleaned and ready for the mechanical restoration device looks like
Restoration and calibration of the chords and tuning mechanism following original instructions
Electronic restoration implies the substitution of all condensers and of other risk or outside tolerance components
Sometimes it is necessary to restore alimentation or output transformers following building techniques of that time
Components can not be judged based on their aspect. This condenser is perfect on the outside and has a brand value of 500 pF and an effective value of 1412
The diodes bridges are almost always used up, they are disassembled and reassembled with the necessary alterations to bring the tension to the levels required by the project
On the electrostatic loudspeakers the membrane or the elastic absorbent are substituted
Sometimes some parts need to be completely rebuilt
Some loudspeakers are blocked or distort the sound. They need to be reassembled after mending the damage
Often the potentiometers are blocked, interrupted or oxidised and they are disassembled and mended
The tubes are tested one by one and, when necessary, substituted
The record players are restored and tested
Lastly: the calibration of every stage following meticulously the manufacturer’s instructions
UPGRADE - necessary accessories to interface radios with outer devices, headphones, record players, CD players, MP3 etc.
In order to get to these results
Or to devices with mirror finishing touch
Or with a finishing touch that makes the beauty and the scent of wood stand out
Creating wonderful objects that furnish a luxury place with class
