you could mount the small Xformer inside your empeg

Well... maybe. Probably. When you say transformer I am assuming that there is an inverter and some A/C current involved somewhere along the way. I would want to be very sure that that A/C wasn't setting up any interference inside the empeg that could introduce signal noise into the output.
