I actually just recapped a set of esp6a's. Kinda kicking myself for not taking pictures of it. I also replaced the resistors. If I knew more about replacing the diodes I would have done those as well.
Can you describe the distortion you're getting? Is it during certain frequencies or volumes?
Well the rolloff both low and high is quite BIG.
No basses, dampened highs.
If i try to crank up the volume from the amplifier, then the whole thing distorts badly..
EG: the bass from drumkick "farts out..."
