Hi all,

I have build several versions of P3A, and i am happy with the sound and all, but..

It is impossible for me to get more than 30 v pp swing from the amp before it clips, and i was hoping for some more. When it clips it is symmetrical.

My rails are at +-42 volt and the PSU is standard with 2*4700uF.

I have tried to feed to voltage stage with a current source and with botstrapped resistors - its all the same.

Does anyone have an idea ??

Thanks and kind regards,

Stormo
