Do you have one of these? How about an ESR tester? Cause I'll tell ya if you do not, and further more if you think a cap is shorted and don't know how to figure that one out, you might wanna start with some electrical theory first.
Know how to discharge capacitors and know to always 100% of the time check their voltages before proceeding, and why.
Other tools you'll need, a fused variac and current meter on your power inlet, and ideally a current limiter there as well. You'll need a good scope and I'd say at least three multi meters. Also a couple mA meters for the output stage.
Does any of this make sense? I know some folks here may come off as jerks in that we don't want ya to mess with your amp, but it's only because we A, don't want you to kill yourself and B, don't want you to make a future Tech's job a royal Peta.
If ya really want to learn to work on your own gear, it's all good, but there's right ways and wrong ways to go. Also just like learning to do fretwork I always recommend starting somewhere cheap, cause odds are as we learn we make mistakes.
That said with amps first things first you need basic electrical theory, and if ya didn't get it in highschool some basic algebra prior to that. If you don't understand the basics, it's like trying cut a board with a cheese grader.
