I am not a qualified electrician, and I'm assuming the answer is "no", but would it be possible/practical to DIY a service outlet into a Spooky machine? In my Alice Cooper's Nightmare Castle there are switched phase and neutral wires coming out of the power supply to figure-8 cable (for a small 12VDC(?) power supply). Those wires could be connected to a surface-mount electrical outlet, and a ground wire could be run to the back of the IEC socket. Plug in a multiboard, internally power the PinStadiums, something, PROFIT!
