I have an older Marcom Stereo generator (FM).
I do not plan on starting a LPFM station, nor do I mess much with RF stuff.
Is there anything else this box is useful for ?....or is it destined for one of my wicked scrap parts tear-down ?
(picture a view from behind me....nuts, screws, wires, and capacitors exploding outward, from my frenzied dismantle.)

If it works, why not sell it to someone who can use it and use the folding green thus generated on a pet project? I hate to see something potentially useful get torn down for scrap.
Stick a scope on the output, and see if a 19khz signal at lowish level is present when switched to stereo mode.
Then stick a 100Hz into ONE or the inputs and check that you get something that looks like a 100hz on the scope with the space between the waveform and the zero reference filled with 38Khz sine wave, you will see what I mean.
If it does that for both inputs, and has the 19Khz present, then it is most likely working.

It is not a transmitter. It only multiplexes the left and right
audio signals and generates the pilot signal for stereo.
Were you needing a schematic for the or a transmitter?
