How can you tell if a capacitor needs replacing?

[J M Fahey]

Hi Posegate, your question is *very* generic, the answer must necessarily be so:
*every* component is there for some reason, it must "do something".
If you know that it´s nor doing so, either marginally or catastrophically, then it must be replaced. Anyway you should try to find why that happened.

What I mean is, what symptoms would an amp produce if, for example, the filter capacitors needed replacing?

[Brymus]

It would have way more ripple and hum and sound farty and loose.

[posegate]

So if volume/gain (is there a practical difference?) were strictly the problem, what should I look at?

Hi posegate,
                 Would be better if you just explain the symtoms you have noticed
and then you might get closer to fixing the problems you are having.
Cheers Phil.

The main issue is that there is very quiet.  I replaced the speaker, which helped a little, but there's still little gain.  I have everything cranked to 10, and still can't hear it above an acoustic guitar.
