I need a schematic and owners manual (if available) for a Silvertone Neutrodyne 1920s 5-tube battery radio.
I NEED THE MODEL NUMBER of this radio to order a schematic –
I cannot find the model number on the radio.
My radio has five Silvertone 201-A tubes.
I can send photos if you give me your e-mail address.
The radio is in truly excellent condition from an appearance standpoint.
FRONT PANEL CONTROLS:
Three large knobs, marked Tuning Dial 1, Tuning Dial 2 and Tuning Dial 3 – each marked with an ark 180 degrees over the top of each knob, with numbers 0 to 100.
These large tuning knobs all rotate large air variable tuning capacitors.
At the lower left is a small knob marked Control 3, which turns a rheostat,
At the upper right is a small knob labeled Control 2 which turns a rheostat,
And the lower right is a small double knob labeled Control 1, which turns a rheostat – there is a smaller knob inside the larger one
