Circuit diagram for this radio is at http://www.nostalgiaair.org/PagesByModel...013252.pdf
I have completed restoration of this radio with new electrolytics and replacement of paper caps and out of spec resistors. It is playing good. My question is about the "shadow meter", item 27 on the circuit diagram and parts list. This is supposed to provide some type of visual tuning but I see no change in the shadow when tuning a station. How is this supposed to function and are there any ways to test it. The coil portion of the meter measures about 1450 ohms.
Thanks, Bob
