I have a PSU (Power Supply Unit) that has a 230V input.
Now so I'm told, this thing was running a 13.8VDC 2metre Ham transciever.
The tranny in the PSU has an output of 38VAC and the wires in the secondary are very heavy (suggesting a high VA rating).
The transciever itself required 9A on full TX (transmit), it is FM not SSB or anything like that.
OK, the PSU has been modified about 5 or 6 times from what I can see, judging by the age of the wiring.
What I am willing to know is this:
It has 2 Series Pass Transistors, I guess to maintain a high current to the output.
Not having hooked the original radio set up to it, to save damaging the thing, is there a way that I can re-wire this PSU to give 13.8VDC.
One other thing is the fact that it has rectifiers that I've never seen before.
Naturally there are 4 of them and they are made by Toshiba (Reference No. 6CC11) they are a pink/orange colour.
There is also a 4700uF 75V Electrolytic Capacitor in parallel with the Diode bank.
I'll upload some pics tommorow and let you folks have a look at what I'm talking about.
Any help would be cool though.
