Chase,
If it turns out that you have a transformer down, I have one that came out of my MonoPoly. I'm in the UK and my MP was for the US market so I changed the transformer for one with a 240V UK primary winding. The one I pulled out is marked with the following so you can check against yours:
BANDO
TA-006
BDI4B2-003A
Those three markings are on the left hand side and:
61-7981
100V
41.0V 37.0VA
These markings are on the right hand side.
