Hey guys. I just recapped my 212-75. All electrolytics were replaced. The only discrepancies were the two 400mf 25v caps. I replaced one with a 420mf and the other with a 440mf. Also replaced both driver transistors.
When I powered her back on, I got nothing but a loud hum. One power tube began quickly red plating. I'm not sure how to proceed. Any advice?
