The power supply in my APB is dead, and I have an extra Peter Chou style power supply on hand and I'd figure I'd use that. Are there any special considerations for putting this in? Anybody have a guide?

If it involves some hacking, does anybody have a spare power supply I can throw into my APB?
 
Schematics for the APB:

Red/white= + Sense
Red= +5V
Red= +5V
Brown= Ground
Brown= Ground
Brown/white= - Sense

I hooked up the 2 brown wires to grd (-5V) and the 2 red wires to +5V on my AT computer power supply. Works great.

I left the 2 sense wires disconnected. Don't know if I need them or not, but it works fine without them.

Also, if one of the marquee lights always stays on instead of blinking, you probably have a bad triac. I do have a spare left.

Awesome, thanks.

I don't think you need to connect those sense wires. I heard somewhere that it's unnecessary.
