Questions about 19AP4

I believe you could also rig up a 5PF7 radar CRT in a pinch. The phosphor will be weird, but they're cheap and work fine for initial power up and troubleshooting.

Cool. Unfortunately I do not own either a 5axp4 or 5pf7. Will need to study the 10bp4 data sheet to see if HV and other voltages would be tolerable I suppose. Otherwise, I’ll just need to be extra careful testing with the rather unwieldy 19ap4 on my bench.

I’m mostly concerned about safety when handling the crt in and out of the chassis after being charged - where/how to discharge the metal cone crt and make sure I don’t get bit.
