The burst at the APC switch and horizontal pulse waveform on A6 are per the schematic. I will post a scan of what i am working from.

I assume this would clear the 9-37 module as bandpass amp is feeding the burst in properly.

Question: Is the ACC circuit a possible issue? If not, the 221-42 IC may be bad on both modules, though I swapped them with little change.
