That seems high for me, try this approach. 1. Lower the valuue to about 28ma, then from there raise it a little, maybe 2ma play it for a while and see how you like it. Raise it another 2ma to 32ma and play it again for a bit. Try to keep it below 36ma. For me when biasing amps every amp I have ever used gets to a point where it starts to thicken up sound wise, I almost with out fail like the amp set slightly below this point. This is usually middle to slightly cool for the tubes, biasing tubes to the point where they almost red plating is a dumb ass approach IMHO and does nothing to help your tone.
