10 years a go i posted on this thread
SOZ is rad amp. SOZ is BIG amp! no getting around the need for dissipating lots of heat.
Mount power resistors on their own heat sink. Then FETS don't have to share. put a fan on them if needed. Big PSU too
i'll check back in another 10 years

So, tried "Half Son of Zen"
Had the parts, and did not take to long time to build
It plays music but should probably have 8ohm resistor instead of 10 and higher PSU voltge to get "sweetnes".
Know you guys in here said so, but had to give it a try!
Gain is also very low.

got them
looking for magnifier glass
Think it`s PSU ripple making noise.
Maybe build CLC with big chokes to get ripple down.
Hum is not that loud, but nice to have a silent amp!
Use a RC filter for the 100k+47k resistors. Humm gets into the signal through those.
Ok, thanx!
But how without decreasing sound quality?
Best

Sorry for my paint skills
100ohm, 100uF maybe
Why would it decrease sound quality? You are only filtering their supply.
Like at jlh, here a lot bigger resistor is used.
Possibly you could also use 1k or even bigger resistor for better filtering and bigger cap.
