Im not sure I am following, I have not cracked it open to see how it was wired, but what I was thinking (without seeing what the on/off control actually looks like - is it double pole or single?) is thus:

polarity correct a plug, where neutral is tied to the chassis - if in fact the chassis is part of the game (dunno yet, but lets assume yes)

hot to the on off. fused. then the other side of the on off to a 120->6v xformer AND, for arguments sake, ab out 150-200ohms of 10W cement.

Take the backside of the cement to a rectifier...half wave ok, but im thinking a full wave might work, since neutral is fixed, the hot side would be +/- line, minus the effect of the resistor (I need to draw this out to make sure I am not stupid) ahh now I see, the value of '-' from the bridge is not the same as the neutral of the AC line...ok back to the drawing board...but the bucking idea for the xformers is interesting, I have 1000ma capable 6, 9, 12, 15 supplies in a box....many dozens.
