Hey all, A mate of mine has one of these monsters and he wants to look at taming it down some. It is stupid loud at 3! Is it feasible to run 6v6 tubes in lieu if the 6L6's? He doesn't have the cash to buy a new amp so wants to look at potential mod options which I am happy to do for him. It runs an 8ohm speaker but has a 4ohm tap on the OP tranny for ext speaker use. I was thinking about disconnecting the 8 and using the 4ohm tap only to deal with the impedance mismatch from the tube change. It is bridge rectified with 430v B+ according to the schematic. It has bias adjustment so I can hopefully rebias to a suitable PD.....if not perhaps look at the tough JJ 6v6S tubes. I guess the other option is to build an attenuator? What do u guys think? I have the schematic in pdf but can't find a decent hi-res pic to post for reference.
