Re: Roberts R200- Distorted Output
I tried an 8.2k resistor in there and I can now get the bias up to 4mA OK with the AC128 in there. I think I will try it with a silicon diode and do some tests though just in case it does work, silicon diodes are a lot cheaper than AC128s so it would be good if it does work.
The voltages were measured with positive probe to chassis. I had the same problems with the original transistors which is why I tried replacing them, with no luck it would seem!
