Sanyo EZ20 100V?

[Tarantulas]

In a DK cabinet, does the 100V for the monitor just come straight off the stepdown transformer, or is it coming from the PSU?

Where is the best place to buy a replacement 120V to 100V transformer?

[iankellogg]

there is a 120 to 100V isolation transformer. The transformer has a dedicated line that the power supply is attached.
There are 2 2-prong sockets where the marquee light and monitor plug in.

So in short, the monitor does not go through the power supply

Where is the best place to buy a NEW 120V to 100V transformer?

Should I even worry about replacing it?

Odds are it's fine. It typically reads about 108V or so when tested with a multimeter. If you have one, I would just test it.
