I'm in the process of repairing my Yamaha AV amp. Figured I could upgrade the original Sanken 2SC3856/2SA1492 jobbies to OnSemi MJL21194/MJL21193's. But there is no space for the On's: the Sankens are much smaller in size. So now I'm looking for two pairs of these Sankens. Problem is I suspect that the guy who previously repaired my amp was given counterfeits. Classic symptom of counterfeits is that they blow the moment you turn up the volume too much.
Any leads?
