GE 9T001. Hotpoint 9S101 - retrace lines

[JerryR]

Neither set has a decent picture with the antenna connected. The horizontal hold doesn't seem to make any difference.
How do I go about setting the filament voltage --- ?
(Be careful teating those 9QP4 picture tubes. They operate on a 4 volt filament voltage at 300 ma. Make sure you set the filament voltage before connecting to a tester).

Thanks,
