Does anyone have a schematic for a Airline (Mont-Wards) Power supply 62-6626? In my basic checks, the voltages are way off. The A voltage is on target, but the B volt is double, nearly triple the value of the terminals specified volt, ie 45 volt term shows 109 volts etc. I would like to recap but it seems some one did this already did this. But the caps look suspect, but alas with no schematic to reference i have to take the previous techs word for it. I would appreciate any help on this one. Thanks Bob B

Are you testing the power supply standing alone? Or is it under any load? The B+ supply may be correct with no current draw the way it is, but when connected to the radio the voltage will come down to the right level.

Hi Warren, I tested both ways and the voltage stays up there. I checked the big wirewound resistor and am getting resistance that steps down when I check each point, but again without a schematic to reference, I am shooting in the dark.
