thanks all for coments.
i made PCB boards my own ( not realy big problem)
yes a use capacitor multiplier psu beacouse sounds better in this amp.
but this is a realy low cost project so the capacitators and resistors are not exotic thinks.
some day i will change output transistors with mj15003.
the sound is quite good exept power. but for normal listning is good. in sound quality bits rotel rb981 amp. better space, trebble..
