Junction of Q701 / Q702 is supposed to be about 0.60 volts NOT 60.
Also base of Q706 is supposed to be 1.5 volts NOT 15

Anyone that has an A series amp with a PC702 board take note. These measurement are from a working 100% good K200A-1 amp I have on the bench right now.

Not recommended to chance running the amp with that diode out of the clip. Chance of both sides firing at the same time too great for my comfort zone.

Congratulations on the progress.
