If the voltages are the same (outputs to all the boards), I don't see why it wouldn't. Most all pins use the same type plugs, Molex.

A non-DCS transformer can be used in a DCS game, but will overdrive the amplifier supply, delivering approximately 50V to the TDA2030, which is only rated at 36V.

Martin (of Pinbits fame) created a great resource here.....

Will it work? Yes. Will you damage your sound board? Most likely.

My IJ came with a Funhouse transformer, and the sound board was damaged. Perhaps it's a fluke, I don't know for sure.

It also looks like there is a difference between the BOP (and possibly FH?) transformers vs the other non-DCS transformers. My BOP transformer does not have the 2 wire purple plug for the 100V (presumably since it is one of the few WPC games that does not have a DMD)
