I built a universal adapter for my B&K 467 CRT tester and hooked it up tonight. I have heater-to-red-cathode leakage, so I need to isolate the heater connections. All three heaters light up, and the blue, at least, does show some emission. I did not want to turn the heater voltage up to 6.3v until I get an isolation transformer on there, though.
Do any of you know if I could use an isolation-only booster for a B&W CRT for a test? I do have a couple of them here.
