Hi everyone. I have Audiolab 8000A which has blown one channel. The transistors are Sanken 2SA1216 / 2SC2922. I replaced them with the same, but they burned after 3 minutes of operation without overheating and 30% volume! (apparently were fake).
I have the original Toshiba 2SA1302 / 2SC3281 in which base/collector/emitter are the same positions.
The question is: Can I put Toshiba instead Sanken?
Thanks in advance!

There's some reason the channel blew. I'd suggest testing with a dim bulb tester and checking all the voltages and biasing next time, or you might blow more transistors due to the original fault.
The 3281/1302 are higher gain I believe - you will need to re-bias anyway after changing transistors of course. I'd wind the bias right down before powering up with new transistors, then adjust carefully.
