I'm working on a Technics audio amp from the late 70's with blown outputs. I've found one source (in Europe) for these transistors, but they're asking $20 each for them and I am concerned about counterfeits.
They are 150V 10A 120W, with an f(T) of 50MHz... they are faster than anything I can find out there.
- Is it important that I replace them with units with comparable current-bandwidth product?
- Can anyone recommend a substitute? I was thinking maybe MJ21195/96, but they're only 4MHz.
- Can anyone recommend a source for NOS Jap transistors that sells these?
Thanks Dave
