The electron beam is hitting internal metal elements in the gun. Eventually, metal will vaporize and reposit elsewhere. Potentially causing a splotch on the screen

No joy...and I was pretty comprehensive. So, I have sound, high voltage at 8kv, and a glowing filament in the 10BP4. Does the HV and the filament mean I should get light on the screen if I find the right place for the ion trap or should I check into other things and make sure they are right first? The 10BP4 is a good tube...I have used it in another TV. The components are mostly original but there has been some tinkering in the past...rectifier swap to 2 1N4007 with a dropping resistor and a couple of waxies replaced but that's about it. The TV was brought up through a light bulb series and now it's fine on 117 line AC and pulls about 1.25 amps.
