Hey, I am doing some repairs on a yamaha b2x, and I have replacements for almost all the burnt transistors. Except for 2sc3345/2SA1328.
I have a hard time finding something that is:
pretty linear
have a low CE sat rating (around 0.5V or lower)
keep hfe around 100 at 8A
ft fairly high, atleast 30MHz.
have a complementary part.
Any ideers?

Fairly straightforward to replace; 2SC3345-O npn transistor complementary pnp, replacement, pinout, pin configuration, substitute, marking C3345-O, equivalent, datasheet
The transistor is not what has to be linear, that is all done by the feedback loop, as long as the Hfe is equal and not too higher value and the voltage/current ratings are equivalent, all should be fine.

I didnt konw that page, thank you.
However, the big problem is actually finding one with a low CE sat rating, normally it doesnt matter that much, but in the class a amp in the b2x the supply voltage is 4ish V.
but I will have do dig through the alternatives shown on that page, and see if any of them is suitable, and still posible to get.
and i prefer to get as linear as posible transistors if possible.. there is no need to inject nonlinearities if it can be avoided, even though the feedback corrects some of them. Also i build amps with no feedback, and i often buy extra transistors for my stash.. so again migth aswell get them as linear as possible.
