One of your kind members directed me to this forum for further guidance. Feel free to copy and paste/send a link if my questions have been answered a dozen times but here goes...
For a few years now, my Sansui amp has been kicking off intermittently. It currently is emitting a ferocious crackling and popping through the left speaker whilst the right one is okay. I assume the speakers are not the problem as when we plug headphones into the socket, we get the same terrible noise. I have tried outputting from both sets of speaker connections but the growling is still there.
I opened it up six months ago and found the capacitors were a bit leaky so I replaced them but it didn't solve the problem. I tried changing the speaker cable but that didn't make any difference.
One of your number has suggested I need to replace the transistors so my first question is: Do I replace ALL of them? It hasn't had an overhaul for at least twenty years so it could be worth doing but if I one fails, how do I identify it? I could do one at a time, but that would be a pain.
Second (maybe third) question: where do I source the correct replacements?
I've had this amplifier for years, it's mostly great and I'd like to keep it rather than starting again. I've not been able to find anyone local confident in fixing it so thought I'd keep trying to repair it myself. I'm usually pretty good at these things but my husband disapproves of dismantled electronics on the dining table so the quicker I sort this the happier we'll all be.
