Hi,
Can anyone recommend which transistors to use to replace the 2sd234 output transitors on the power amp board in the QL-600a (AWH-005 - it's the same board in the SA-500a).
I already tried ksd526 but these don't sound good. It's very distorted unless I turn the idle current up to around 80mv, then the amp gets too hot.
I switched back the 2sd234s in one channel and idle drops to 20mv (without adjusting the trimpot) and it sounds good and runs cooler.
Thanks!
