I have a Marantz 2252B that has no bias. It keeps blowing C739 (1000uf 16V). I've replaced it with a Nichicon 1000uf 25v, but it keeps popping. It's probably something I did. But before today, it had very low bias, but not blowing that cap. It sounded good, but not in good health with low bias. Today I changed out Q743, 744 with KSC945ybu transistors, and was careful with the E,C,B orientation. after that C739 started blowing. I had changed bias and DC trim pots already. I'm just getting a little frustrated on this one. Figured I'd ask for help, while I step away from this thing for a day. Thanks to all thats willing to jump in. LOL
