I traced the tracks as best I could, and it appears that the less powerful output is the one with its own power transistor.
The 15A one had some very narrow tracks too, so narrow in fact that I felt a little foolish and read the label again, expecting that I had misread it and it was in fact...
Thanks so much for your help everyone, as you can probably tell, I'm rather the enthusiastic amateur when it comes to power supplies!
I remembered that one of my friends had an old pc in his garage, so I bribed him with beer and got a new power supply.
This is a big deal, because this supply has...
I guess I'll add a resistor just to be on the safe side then, it's not like they are expensive or difficult to install...
It's too late to use multiple wires on the +12v 4.4A rail because I cut them off, but I'll desolder it and use a thicker wire instead.
On the other rails, there were two...
No, the chip is an AS2350C, which appears to be a specific Astec chip (the supply is made by Astec).
I ended up desoldering the +5v and COM wires and replacing them with nice chunky 14 gauge wires. From the specs I have seen, this should be enough even in the unlikely event that I manage to...
That's odd then, from what I can make out the supply is from 1998, so it would certainly class as 'older'.
One more question: In the tutorials I have read, most of them say to bundle all of the wires of the same color together and attach them to the binding posts.
I presume that this is because...
I have an old PC power supply, and I'm making it into a bench power supply.
I'm not sure what type of psu it is, I think it's a propietory one (HP branded).
That doesn't really matter, because I have worked out what all of the wires are and it works great.
One thing that is puzzling me...
