An update. I remembered that when I was working with this set a few years ago, I would get a better audio response from a VCR rather than a DTV converter. I connected up the VCR and with the contrast control all the way up, I could hear faint audio under the interference. Since the chassis is in the cabinet, I did a rough "ear alignment" (as Phil calls it) and was able to get a sizable increase in volume. (I only adjusted the top two coils, as the third is accessed from the bottom. I will adjust this one as well when I pull the chassis back out for the formal instrumented alignment) The first IF coil has a silver mica cap in it, while the second uses a tubular ceramic.

This reminded me of a quandry I was dealing with back then: If I used a DTV converter, I'd get a nice picture, but no sound. (Even with the contrast turned all the way up, which functions more as a gain control in this set, the sound is absent or very faint. The contrast is set around the middle of the range to get a good picture with no distortion or retrace lines.) If I used a VCR, the sound signal is stronger, but with the contrast dial turned to a point where the audio is a decent listening volume, the video is overdriven and distorted. I wish I could get the good video of the DTV, but the sound of the VCR... Any ideas as to what else I should be looking for? (Yes, I have the sound control on the DTV converter box turned up to the max) I also want to put a signal directly through the amplifier in the lower chassis and verify that nothing has weakened in the main amp itself.
