Nice board

Well done

Is it a mosfet or bipolar amp ?

It's an amp based on IRFP240/9240 mosfet, it push out about 500w rms on 2ohm per channel!
I and one my friend have designed the circuit and i have designed the layout, all the work was done by hand, no pc layout!
It sound very good without noise and bump, the s/n is over 120db!

For the PSU i use one 625va trasformer for each channel with 20.000uF for +vcc and the same for -vee, 80.000uF in total.
