Re: Where should an isolation transformer go?

Lewis. You should not need to install an isolation transformer. Leave
the stock sega transformer in place to supply power for the monitor (90
VCT). You can connect the switcher to one of the leads for the cooling
fans (to the card cage for example). Replacing the power supply is a
good idea even in a game that has an original working supply, But note
that not many video game specific supplies provide the -12V the sega
vectors require. In the past I've used old PC switching supplies with
great success. Also note you should tie the white wire (3VAC) going to
the original PS to +5VDC on the new supply.
