Hi guys,
(I'm a real newbie, so please be indulgent with me )
Someone gave me a SE EL34/12A*7/5AR4 amp.
It sounds quite good but one channel is louder than the other, particularly in the mid-range.
I swapped tubes, swapped and changed the 12A*7; the only one I didn't change is the rectifier.
I interchanged my speakers; I tried the amp with another pair of speakers. I swapped wires and changed them.
I checked soldering, resistors and caps. Everything seems OK. But obviously, there is something wrong. Because one channel is always louder than the other.
The next step I should do is checking transfos. Gosh. I'm not really sure what to do about that...
Before this step, do you think I could do something else, that is obvious for an old DIY pro but unevident for a rookie ?
I know I should have done the schematic, but I didn't
Thanks a lot
