Cold bias on Epiphone Triggerman

[drewl]

Well what I thought was a blown speaker upon further inspection is bad crossover distortion from what i imagine to be coldly biased output devices.
i don't suppose amyone has a schematic so I can try to adjust the bias eh?
Any one else work on one of these?

Hope these help

I do not see an adjustable bias.
Time to check transistors.

Bias, or maybe one side not working.

Oh hey, I never checked back so I wanted to thank you guys for the help and Ted for the schem.
Looking back it looks like R318 1k in parallel with R35 10k was actually a 2.7k resistor.
I had lowered the 10k to another 2.7k and that helped alot.
Thanks again.

Thanks a lot, before changing R35 to 2.7 K my amp had a buzzing sound. Now it's clean, my R318 is 1 K.

By the way do you have any idea for removing the hiss from the dsp effects? The flanger and chorus are unusable because of this.
