'49 Admiral audio problem

[kbmuri]

Einar72, your prognosis seems logical. I was thinking the audio IF Frequency was just off and I wasn't tuning the sound carrier, but your explanation makes more sense. Unfortunately I recently smoked my vectorscope -- just bought an eBay replacement last month, but it needs a recap. It's annoying when you have to fix your tools before you can fix your toys. I'm working that problem first, then I'll post a shot of the response curve.

El Predicta, thanks for the extra info. The sound loss is identical on channel 3 and channel 4. This suggests the problem is after the tuner turret, but I will still adjust those coils, last, using my signal generator, centered on each channel frequency range, for the channels other than 3 and 4. I'm doing this one for a friend, who will be hooking it up to a cable box, so channel 3 or 4 is probably enough.

Thanks for the help!
