I picked up a mint 555ii last week and I'm just going over it. I did some measurements on the four big filter caps and it seems one of them may be dying. They are the original Adcom 15,000uF 100V caps.
1. 15.96mF, ESR 1.2ohm, Vloss 0.9%
2. 10.16mF, ESR 1.2ohm, Vloss 1.6%
3. 15.92mF, ESR 1.3ohm, Vloss 1.9%
4. 15.36mF, ESR 1.2ohm, Vloss 2.3%
Questions are would it be ok to leave things as they are, or should I replace cap #2 or replace all four.
The amps sounds perfectly fine as is and is very powerful.
Thank-you in advance.

I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
