Just a while ago my stereo started smoking. I took it apart to see what was wrong and i found 2 SV31 biasing diodes that werent heatsinked good. I thought forsure that this might be the problem but when i tested them with my multimeter, they tested okay. Should i go ahead and replace them anyway
I have a realistic sta 7 receiver it just started doing this today but the speakers were humming
