sorry, i don't actually "see the signals" (bad use of words here). i can trace the circuit and see where it goes. what i can't seem to determine is why only those functions do not work. the only thing i see in common is they are on the same part of antenna board. i just don't know where to...

hello, it's been awhile since i've posted. still working this refurbish. replaced the function switch but still having problems with FM Mono, FM AFC and AM working. i've tested the voltage on the paths as documented in the schematic and it appears i'm getting power thru the switch to the FM Mono and...

hello all. i was able to find an old chassis online and have salvaged some parts. i now seem to be able to receive all bands and the stereo indicator light now works! however, still having the issue with sound only coming from the FM Stereo, Aux and phono. any thoughts on why AM, FM AFC, FM standard...

Looking specifically for a multiplex switch and transformer.

Sorry. Chassis is R210401-AA

Thanks MattTech, this is very helpful. i've verified the bulb is correct, but upon further inspection, i noticed the print board where the wiring for the indicator light is connected is damaged. do you know where i can find a replacement board? for the other issues, i inspected the multiplex switch ...

Thanks for the reply Ron. yes, it has a socket and it appears in good shape. i've replaced the original bulb with the same bulb (mfr, model, size, etc.) so assumed it would work. going to check the actually socket itself, but i did re-solder the wiring. all the other bulbs are working, so it appears...

hello. i'm in the process of refurbishing a 1966 Astro-Sonic. I've recapped the chassis and it appears to receive all bands. however, when i choose the FM Stereo, the indicator light does not work. i've traced the wiring back as best i can, and re-soldered the connections, but it still does not work...
