So surfing ebay, I spot this nice Stargate cabaret, and stop to examine the pics.

This unit has a Defender style power supply, I suppose that is what shipped in the Cabaret cabs. On the out bound power header there is a daughter board; I have never seen this before, anyone know what this is?

Item number: 130311382525

Stargate added a little board with SCRs to shunt current to ground in overvoltage conditions to protect the board.

The SCRs were added stock into the design of later supplies..
 
I have one sitting on the desk, if you want to see one next time you stop by.

They are known as "over voltage protection" boards p/n 5773-09664-00
