Thanks for all the help fellows. I will contact skipp and see if he has the reg. board for this unit.
I made the mistake of hooking the power supply up to a car battery - backwards - and poof - all the smoke came out. From what I can see C6 on the reg. board is blown - the bridge rectifier is ok, and there is about 22 volts DC getting to the reg board, but it stops there. The board number is 66-214D if that helps 73 Ian VA2IR --- In Repeater-Builder@yahoogroups.com, "Mike Short" <[EMAIL PROTECTED]> wrote: > > I am in the process of repairing a Tripp Lite 50A power supply. > I bought a regulator board from Skipp, who frequents this site, and will > graft it in to the power supply in place > of the defective one.
