Trying not to get discouraged about this problem.
I hauled out and recapped my old never-tried EICO 360 sweep generator and got it to light up, but don't have any way to tell whether it works properly. I tried going through the sound alignment drill, but couldn't get anything resembling a useful display on my oscilloscope.
This was feeding a 21.25 mhz marker signal into the sweep gen with my old but working EICO 324 signal generator. I can verify the setting on the sig gen with a digital SW radio.
Cautious twiddling of the sound IF and discriminator transformers didn't make any noticeable change, so I set each one back to where it had been.
Just as before, I can tune in FM radio with decent fidelity and volume on some stations. But the TV is silent when fine-tuned for best picture. And I don't get TV sound on any channel.
The solution is to buy a new sweep generator, I suppose. But it's frustrating to be totally blocked in the meantime. I wonder if there's any way I could do an approximate alignment of the sound IF using only a signal generator and scope (or multimeter, for that matter).
