Peavey Heritage VTX HELP!

Have this amp.. came to me with a bad distortion at all settings. Opened it up and found R3 (100 ohm 5 watt) open. Replaced it - no change. Replaced the 2 6465 transistors (Q9 and Q7) on a whim.... no change.

I am only getting 108 volts to pins 1 and 8 on the power tubes. I am getting 522vdc at 3 and 4.

I'm thinking now that it could be the transistors Q6 and Q8, but I do not know how to effectively test these and of course I am not sure these will do the trick anyways.

Any help would be much appreciated.

Replace Q6 & Q8.
A 2N3904 will work just dandy.

Hey, I am not that old.
(how do I change that pesky title)
Rather than replacing parts willy, nilly (I love that phrase), you really should observe the voltages that Peavey so kindly indicates on the schematic.
