My friend dropped a Music Man 65 head off for me to service and I guess I was thinking it was a little more like a Fender.... I'm getting 688 on the plates!! Anyone have opinions on biasing the EL34's? I'm running it at 22.5 ma cathode current on the hi-power setting and 12 on the low. Is this OK? Also, there are two trimpots. The first is obviously the bias. What is the second for?
Thanks as always!!!

There is a trimpot used to set the "balance" point for the Tremelo. Is this what you are referring to?
