The gate resistor for the output fets are 34 ohms. Wondering can i switch it to a 33 ohm?

That would be OK but if you have to order other parts, order the correct resistors.

Ok replaced all of the following in the left channel

All outputs

27.4 ohm resistors total of 4

34 ohm gate resistors total of 4

emitter resistors total of 4

and replaced all of the following resistors since they were defective

R1036
R1034
R1044
R1047
R1058
R1019
R1015
R1012
R1059

Amp power up and idles perfectly. I get clean sound on the right channel..

Left channel is very distorted and has 0.23 volts on the speaker terminals..

Cleaned all switches and bias pots are fully counter clockwise

Any ideas?
