I need to fix my boost switches on my 2 Sorados. They work ok on one, with little scratchiness and sometimes a bad connect, and the other has bad connects all the time. The treble might even be stuck in the on position, regardless of where the switch is. I would not mind bypassing them all, since I never boost anyway. But then again it's nice to have them if I ever change my mind. Could it be just a bad or dirty switch problem or more to do with circuits too? Also, both amps sound unique. They have different power tubes. One has Chinese 6550s with a 12ax7 and the other has old Magnavox 6550s, with 12ax7. I prefer not so bright a tone, I don't slap bass. I like compression, warmth and mids. What say ye ol master? SteveDePra.com
