An old guitar amp is headed my way, solid state, maybe 50 Watts, maybe a couple decades old. One reads about the finite lifetime of electrolytic capacitors, so I have some questions:
- What are the actual failure mechanisms?
- Is there a convenient way to check an electrolytic?
I don't want to replace more caps than necessary. One website suggests simply following the signals with a scope and verifying that the functioning of the circuit is consistent with functioning capacitors, and I will certainly do this, but am wondering if there are some tricks of the trade to know.
Thanks in advance!
