Hello Again Update-- As you all probably guessed the SK Replacements sold to me by Tritronics as replacements for 2SC3281 and 2sa1302 ARE COUNTERFEIT (they blew after 2 min). I can understand if the transistors came in one of those see through zipper bags, but these have SK on the sealed bag. Attention Kevin, perhaps you should stop saying the SK brand will replace the above transistors, because when I reported that I was going to replace the transistors again on the good side, I could almost hear the collective sigh of everyone on this form as they we saying , don't do that, they will blow. How come almost every tech knows that they will not sub but tritronics does not?

After running for 5 min at low volume they blew. Now I'm thinking these are counterfeit transistors disguised as SK, but in all fairness I will try putting the transistors from the other good channel to the bad side and install ANOTHER set of SK's in the good side and see what happens.
