Interesting! You know everything after the volume control works. layout is nothing special on mine. In fact, since I wanted the ability to turn it back into a normal 70, the AVC line is just kind of supported on the the end of the resistors soldered to the coils. Not real neat and hig quality construction! I was thinking of taking the chassis out this afternoon to test the frequency response of the audio portion. I'll take a couple of pics for you. As I told you yesterday, I left all of the old components in there so there is stuff just hanging unconnected. I was just playing mine, and except for the roll off of the extreme highs, it sounds great.
You WILL solve this!
