The Internal Power Supply in my ICOM IC-751A, the PS-35 has quit operating.
The fuses are not blown. It just doesn't start anymore.
Physical inspection revealed an open solder connection between to
odd-looking transformer devices. Repairing that did not correct the trouble.
I'm told that the usual problem with these switching power supplies is
failed capacitors. I don't know as I don't have much experience with
switching power supplies.
I have the schematic that came with the unit but I'm not familiar with the
functioning of this type of unit.
Is there a source for a description of the circuitry or perhaps a service
manual for the PS-35??
If not, are there any recommendations on where I might get this unit serviced??
Many thanks to all.
