Hi all, haven't been posting for a while but this one has me stumped. I have done a bunch of 2270's and I have a problem I don't think I have had before. (maybe old age is kicking in....)
I just recapped and redid the power supply, relay new output transistors from Digikey and bourns 25 turn pots. Adjusted the voltage and the relay kicks in but on the right channel I have 0.5vdc when starting the dc offset adjustment. It does not change with adjusting the potentiometer either. This took me by surprise and I was wondering if anyone had any ideas. No smoke , just no glory right now.
