Hello Everyone, A Fisher RS-914A amp came in the shop today with blown outputs (2SA1302 & 2SC3281) , looked up my inventory and I have several original # is SK's in stock-- After making sure nothing else was wrong with that channel, I installed the SK's ( the writing was a little different in contrast on the front of the SK transistors but everything else look ok). 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.
