! have 2 BC 779's. One with A RA 74C Pwr Supply and the other with a smaller one that does not have a ID number on it but appears to to a much smaller copy of the RA 74 C. The smaller one works as advertised But THe RA 74 is putting out nearly 2 times the voltqages that the manual says it is supposed to. I have checked all the components and they are exhibiting the proper resistances and the main pwr transformer is putting out the proper 6.3 V for the filiments. Am I missintg something here.??? The power supply seems to be working properly except for the high voltage readings. I am hesitant to plug it up to any of the receiver that I have that use this model supply. Can anyone out there tell me if I have missed something.
