Chuck ,Sorry to disagree with you, have you even taken the time to look at the schematic, In principle yesI agree with you but this supply is different than what you? described.? It uses a multitap transformer to minimize dissapation and a comparator thand maze of switching transistors that is where I suspest the problem lies or the feedback circuit.
Why does everyone state the obvious repeatedly and think I haven't checked it???
I think I metioned several times that I checked everything and cannot find any faults.I know when I turn the voltage up all the way I'm getting? about 15 volts and it should be 31 and the relay is oscillating on and off? about 2cycles a second , What is that, where to look. The problem lies in the op amp area . This is only the main side.what about the slave side which has little to know voltage.
Chuck , I know you know your stuff, and I do very much Thank you fot your input,but I could use one person to walk me through the regulator,comparator error amp ,feedback and such to the output of the series pass transistors.
There are dual fullwave bridges and filters ,bleeders? per side one low current feeding the references the other high current feeding the series pass transistor.
Why isnt anyone talking about that! Im not an idiot!
Many thanks!
Dave
