Re: Repairing a Victor?
Here is my experience in applying reverse voltage to a Victor. It happened in about 2004 so they were Victor 883s not 884s.
A student was building a small test electrical panel for a drive prototype. He wired all 4 Victors backwards and applied power to it before asking any one to check his work. It obviously didn't work on his power on test, so he turned it off and sought help. We fixed the problem and tested the board again. Everything worked for a few seconds then one FETs in one of the Victor 833s blew out. The rest of the Victor's were fine.
We disassembled the broken Victor and noticed damage components other than the FET so we didnt try to repair the Victor. We desoldered the broken FET and screwed it to our workbench as a reminder to check your work.
That is my experience, take from it what you will. Only 1 of the 4 Victor 883 failed so there is a chance your Victor still works, but I wouldn't trust it.
