I'm trying to tame a 50 watt 2x10 Holland Little Jimi. It came set up with 6L6 tubes (Winged C's) and I'm thinking about moving to a set of vintage 6V6s (RCAs or Tung-Sols) to quiet it down a little. I know people with 35-watt versions of this amp have made this transition to 6V6 with a re-bias--the transformers Mike Holland used are up to it--but I don't know how having a 50-watt version changes, or might change, the equation. I'd like to use this in tandem with a 22-watt Bruno Cowtipper during gigs. I generally bi-amp with a stereo Leslie-style pedal. Silverface, this might be a question for you, as I know you're familiar with these and something of an enthusiast. If you have any input that would be terrific.
