Pretty sure that is a Brittish market 405 line AM sound TV set...Wonder what it is doing in the USA?
Looks like it is an AC/DC set. Easiest way to power it is to set it up for 240, and either connect it to one of the stove/dryer/airconditioner outlets you may have in your house, or get a 120V to 240V step-up transformer.
It should be possible for it to sync to 525 line signals.
