Thanks 6l6. I get it. So the orientation of the secondary ac wires doesnt matter? They can be swapped? Just make sure the notched corner is V+ out and opposite of the notched corner in V- out right?

And to find the matching secondary pairs just test w/a meter I suppose.

Thanks again.

Hikari - Yes, the AC on the bridges doesn't matter, but if you can keep them in the same orientation, it at least looks better.

Yes, Notched corner (and it also has the spade lug twisted 90deg to the rest) is the DC positive. Opposite that is the DC negative, and the remainders are the AC in.

And yes, meter the secondary wires, (ohm or continuity) to determine which are the pairs.

Carry on and build amps!

Thanks to you guys, I hooked up the PS to mains today. 25.2V+ and 25.2V-. No burning, smoking or anything. Caps stayed cool.

Couldn't have done it without you.
