Hi!
I have a qustion regarding bias setting for this amp. Both channels were blown, managed to fix that, but dont know how much bias would be reasonable. Curently runnig at 100mA/device but runnig quite hot (cant hold hand on heatsinks). Schematic is for D/AS 1000, mine is mark 2, should be the same except different parts used. Original output devices were 1 pair 2sa1302/2sc3281, 2 pairs 2sa1215/2sc2921, which i replaced with 2sa1943/2sc5200 & 2sa1295/2sc3264.
Thanks

Hello! Unfortunately the images are no longer downloaded.
In the end, how many mA you installed ?
Now I'm working on the same amplifier like your.
You will not share a schematic diagram?
