Hi all, I have recently acquired 6 pairs of the above transistors. Can anyone please help me with a schematic to suit theses transistors? Pulled from a Yamaha amp. Ive googled myself silly and have found nothing.
Are you searching for an amp design using those specific devices? Why not copy the Yamaha amp design that those devices came from?
Hi there, the reason I'm not doing that is that its a six channel single pcb design. I'm looking to make something way simpler.
A Blameless style circuit from +/-55V or so? They are pretty standard output devices, you've a choice of CFP or EF output stage, and consider whether you want over-current protection built into the amp?
You could have two amps with 3 pairs of outputs each, or use some as drivers to give 2 pairs of outputs each?

Hi Mark, thanks for the advice. I haven't designed a layout or built an amp in years, so I'm a little rusty... My plan is to use one complementary pair, I'm only looking at around 100 W max. Do you perhaps have a link to a schematic that would work for me? Output stage config is not really an issue, but all I want is something stable and reliable. I'm going to veroboard it so all I really need is a decent schematic... TIA if you can help. 60 W is enough, in all honesty.
Maybe this thread is useful?
