I am restoring an old stereo valve amp and would like to test (and replace if needed) some components. I don't know the history of the amp, but it's made in New Zealand and looks to be from the 1960's or 70's, but I could be wrong.
There are a couple of capacitors that need identifying. The first and larger one is clearly marked 50 \$\mu\$F, however, it has three legs. What I would like to know about this capacitor is:
- Do the three legs signify a 2-in-1 capacitor?
- What does the product code of
2222 063 90025
signify (tried here, but no luck)? - What do the triangle, square and circle symbols indicate?
- How do replace this capacitor?
