I think my bass player's Sunn/FMIC 300T is just about due for a new sextet of power tubes since the bias seems to be drifting a little much lately. It currently runs the stock Groove Tube 6550's (presumably Sovteks).
Does anyone have a recommendations for new power tubes for this amp? NOS are probably out of reach, so let's stick to new production. JJ KT88's? Svet KT88's or 6550's? EH KT88's or 6550's? Thanks!!!
