Greetings.
I was send to repair the Onkyo HT - R960 as it was having a noise problem.
I listened to the front speakers and at turn on there was loud digital, DSP like crackling which got better after 3 min or so. Then, later on i could listen to music normally for about 5 minutes and it started again.
I was looking at the dsp chip and the components around it and as stupid as i am, i made a short along two jumpers on the amplifier board. I later determined one of the driver transistors had blown and the others were ok. The driver is 2SA1930.
My first question is, can i replace the 2SA1930 with 2SA968? I have it avaliable in a store nearby.
My second question would be if any of you had the simmilar issue i have with this receiver, where did you look ?

Not the same spec, so no.
You'll undoubedtly find you've also took out some low value resistors nearby, further upstream, and potentially some other small(er) signal devices.
A 2SA1930 😉
If you really can't find a 1930, then google will provide suitable alternatives.
