I reckon so...perhaps time to pull out OT and test it again.....
Yes . The protect circuit is likely detecting enough DC at that amplifiers output to do what it is designed to do.Would this cause my relay to not latch....
Probably wouldn't be a bad idea.I guess KSA916 is the replacement. I wonder if I should be replacing the NPN version of its match?
Use TP1 and TP3 for one channel --->adjust VR481
Use TP2 and TP4 for the other channel ---> adjust VR482
Yes. Voltage bounces around from as high as 26mv down to 4.6mv....never steady...dumb question...I'm checking DCv not ac..correct?Did you try this way ?
Correct. Your trimmers might be crap.I'm checking DCv
