scooby214, hi. I don't think minor hum that you discribe is a problem. As with other things in life we never obtain perfection. A little hum is inevitable. I note that you said the "the large filter cap has been replaced". That set has a 30/25/20 mfd electrolytic, all in one can. Do you mean all three caps were replaced (e.g. large = the entire can) or the large 30 mfd was the only one replaced. All the electros should have been replaced. PL
