First is that I cannot get the power supply to regulate. It is delivering aprox 4V less than the voltage that appears at the gates (which I can vary depending on the value of zener diodes I put in the circuit) but it seems to not to be regulating at a fixed voltage as the reg V sags whenever I add load to the output.
Regarless of this. I think I have bigger problems as I brought the audio circuit on-line this afternoon and it is definetly not working right. I have set the bias to aprx 560mv for each side and have my dc offset to within 20mv or so. When I present a signal at the input it sounds way off (very distorted with heavy echo etc.). And if I place a signal at only one channel it comes out of both speakers?
Well I guess I have some rework to do!. Anyone out there have a similar experience. If so I would love some advice.
Cheers
