I'd be interested to see what people are using in the tesla coil arena.
If you know your tester and it's gas test well the more heinous gassy CRTs will have a distinctive fail characteristic.... One nutty thing you could try is to take a monochrome chassis with 20KV or more of HV and connect the CRT leads from the chassis to one gun (with clip leads), then connect the HV. With the brightness at minimum it should produce a center dot on the screen, but if the tube is gassy there will be an arc inside the tube between the HV and the electron gun.

After seeing your center picture Bob, I tend to think the crt has seen better days. Ben I don't have tesla coil tester but I bet your correct about it being a dud.
I find it difficult to get a good picture of the purple glow in the crt gun. I'm still going to recap the chassis and try the crt just for the experience. The last photo is with my camera set for nightime exposure, for more light. Ed |

Thank You gents for explaining and showing pictures of the tesla coil . I have one in my collection that came from the contents of the Radio/TV repair shop I was lucky enough to get , and wasn't quite sure what it's use would be in TV repair work .

You can find "tesla coils" listed as Master High Frequency on ebay. Used in the field of cosmetology and skin care. Make sure you buy a "working" unit. These units heat up and burn out when used for prolonged periods of more than 5 minutes. Dumb cosmetologists often over work these units and burn them out.
You will need to make your own metal pointed probe if you buy one of these with the glass skin care probes. But it is cheaper than paying $250 for a new one. https://www.ebay.com/itm/Vintage-Mas...4AAOSwGJlZL6Bu

Rebuilts tended to arc due to contaminant particles. The Cattle Prod made the particles incandesce and fly around until they stuck somewhere, thus minimizing arcing after installation. Last edited by old_coot88; 02-02-2018 at 01:27 PM. Reason: DUMB TYPO |
