Any progress on finding the sound in pic problem?
If you have a scope, you can look for sound waveforms on pin 6 of V11B, 2nd sync clipper (second half 12SN7). If there is sound there, then it must be a problem with C38 or the connections to C38.
I also see a weird three-way connection to the bottom of R29, with two leads going to the same electrical point in the sound section above. I wonder if this is a mistake in the SAMS. Maybe the horizontal line should be broken between these two leads and not to the right of them.
