Biasing the F5 higher, new trim pots?

I made some resistor changes, recommended by NP, to "warm up" the F"5. It worked very well and I'm happy, but the amp runs a lot cooler.

I have it biased at .59v but that's got the trim pots maxed out, I want to be able to up the bias until the amp runs at a better temp.

I picked up some pots (10k), thinking they were Bourne ones, but found they were copies. Is the quality of the pots essential to the SQ? Or is their function simply to shunt power rather than deal with the signal itself?

Thanks for any suggestions
 
could you post the bias circuit here?..i might can help but after searching the F5 schemes i'm confused where's the bias 😕

and bias pots didnt affect the SQ imo.but they affect the stability of the bias which could affect the SQ..
