hi
after first glance it looks nice, a bit over-complex for the idea- I guess it has developed from trial and errors or quiet sophisticated idea...
Diodes only for protection - am I right ??
How about more complex RC at input ??
I don't like the 10 ohm with 68n cap on the output - the border freq is 200 kHz ? - what for? compensation, filtering, ..?

Nethertheless I am curious about how it sonds
May be really nice

Hi, it is a modified Citation 12 MOSFET amplifier. I've built it (the original), think it's still available on "Pass" site, used IRF 540 on the output, and it worked OK. Then I tried current source and this is the diagram. It is currently working in my living room. It has a very good sound, you can listen to it for hours. Also, it runs cool, and I don't have any protection or delayed on/off. Build it, it's cheap and it works good.
