AI-assisted summary
Description from the seller
SILVERTONE 7085
RADIO/PHONOGRAPH, WIRE RECORDING AND REPRODUCTION DEVICE.
The Silvertone 7085 is a unit that combines radio, phonograph, and wire recorder.
It dates from around 1947 and corresponds to the desktop model, manufactured by Sears, Roebuck & Co.; Chicago, USA.
It works as an AM radio or as a 78 RPM turntable, and it can reproduce and record using wire recording, whether from the radio, the phonograph, or an included microphone.
The radio incorporates a loop antenna and also accepts an external antenna. Essentially it is an AA5 (All American Five); the two additional tubes are used for the preamplifier of the playback head for the wire and the recording bias oscillator.
Sears offered several models of wire recorders. Its high-end models, such as the 7085, were capable of delivering surprisingly good quality, equal to or even better than early tape recorders.
Rescuing this antique unit with its accompanying wire reels offers a fascinating glimpse into the period immediately after World War II.
To playback a wire reel, simply place the spool on the right-hand shaft, label facing up, so the wire unwinds counterclockwise. The wire passes through the playback and recording heads and is wound around the edge of the turntable.
Currently the radio works and receives AM stations, though at low volume. The recorder and turntable operate only mechanically, perhaps due to four years of being stored without use. So, if you want to use it fully, I recommend giving it a small service; I imagine there is a capacitor or some resistor that is not performing at full capacity.
The seven tubes have been tested and all are fully usable (two are completely new, never used).
* Along with the unit, 7 wire reels, era brochures (they correspond to another similar Sivertone model but explain its basic operation) are included.
