yess ... yesss .... it was c100 now the pg506a works correctly !!!!

never happened that a ceramic did so '... usually electrolytic and tantalum give problems
I hope it will be useful to someone .... before writing here I searched a lot on the net but I didn't find much ...

is it normal for Q290 and Q190 to be very very hot?
is there a way to make the output less noisy?
in standard amplitude on 1 Mohm oscilloscope I measure 2 mV P-P
is this a normal value?

THANKS GUYS !!!!!!!!!..........IT'S ALSO THANKS TO YOU !!!!!!!!!
