I'm not taking about CRT testing or restoration there. I'm taking about powering the whole darn TV. You can't power the whole TV from a CRT tester/restorer.

If you wire a 4 wire heater transformer so that one terminal of the secondary connects to one terminal of the primary and connect a power outlet across the other terminal of the seconday and the other terminal of the primary you can make a device that lowers or increases (depending on the polarity of the secondary waveform) the output voltage by the secondary voltage....IE if you have a 24V secondary transformer and a 120V line you can wire the transformer to give you 96V output or 144V output. Japanese electronics designed for 100V don't always like American 125V... bucking line voltage down closer to the rating prolongs the life of the device.
