Good job finding the problem. Sounds like it is somewhere on that page. I would check the transistors with an ohmeter as they are, in place. That may show you something. Another thing to do would be to replace U 801, I did not look it up but it seem to be an op amp. Maybe it is the problem.? Anyway, something to try. Replace C 819, if you have not done that already. That cap and the op amp would make the ramps on the traces for 6D and 6 E.
