I would suggest trying a DVD player though an rf modulator. You could probably even run the DVD player into an auxiliary input on the VHF player and still use it's rf output.

The vertical knob on top does very little as far as I can tell. The flicker doesn't disappear at all, no matter how often I adjust anything. I can hear the feedback in the speakers, the frequency of the hum and the flicker practically sync. Something is causing enough disturbance, and it isn't getting filtered or properly syncronized. Also- the horizontal lines stay no matter what.
I don't know enough to figure this out. Time for the crt to probably rest a bit.
