For the cap voltage rating take the existing values as a minimum, higher voltage ratings will make no difference. Nichicon are a reliable brand and have a wide range of polarised and non-polar electrolytics... look at the 'Muse' series.
Re-capping Modular Component Systems 3222 Receiver
Gents, I just picked up a Modular Component Systems 3222 receiver and it's in excellent shape. Everything is working but I still want to re-cap this thing, mostly for fun and practice but also as a preventative measure for any future problems. It's all laid out really well and shouldn't be much of a problem for me. Any advice on this? I think that I will eave the entire tuner section alone for now. I will only replace the electrolytic caps throughout it. Is it safe to use a higher voltage on all of the caps or should I match the voltage. Any recommendations on which caps to use? I don't mind spending a little extra on some or all of them. Would it be beneficial to use higher quality caps on the preamp and power section? Thanks in advance for all of your ideas.
