Amazing Rubycon Black Gate F Cap

[richardjhy]

Servicing Yamaha A-1020 and trying to recap then found Rubycon BG F caps are in amazing status after 40 years. The cap measured in the photo is rated 1000uf 25v. Looks it never get aged. I'll keep using it.

Or, it could be degraded and leaky . . . Those testers ignore leakage, which can raise the reading.

I recently took some out of a Rotel power amp. The ones in the coupling cap(easy life) positions measured spot on. Still replaced with Nichicon Es.
If anyone wants them to use message me.

I have to be honest with myself. If I unsolder a cap, it’s going to get replaced.... hmm.... 99.99999% of the time. Give or take.
