Capacitors 101
TV on bench with vented main filter cap, (220uf @ 200v), and I've a
simple query. Can I up the ante on this and replace with a 470uf @ 200v? It's a switched mode p. supply and the pop was a result of a power surge, didn't take anything else out. Is it just a question of economics when it comes to filtering, (cheap walmart tv), or might I disturb the fragile balance in the smps. My thought is, better filter, smoother dc. Any thoughts??? Cheers, Steve |
