Now the amps runs @50ºC stable, measured at the hetsink,
just nearby the transistors.
The bias is now 200mA, and i noticed a slight sonic improvement..
Thank you all for the help!
-another Q, i believe the DC at the output is a little too high, how should i adjust this in a proper way? maybe incorporate a potentiometer at a tactical spot in the circuit? 80mV doesn´t sound very good to me, i´d like it to be much lower, help please!!
