Well I had the plans for the mask but I think it's a done deal because I really don't want to change much in the set with the higher cutoff voltages of the pilot and I'm not sure how to modify it simply to get it to work.

I would agree. There's still many of those Pilot TV's around in various states of repair. You might try to nab one with a rough cabinet for a reasonable price and hope the CRT is good. I know someone who haggled for a very nice one at a local antiques shop recently - he got it for $75! - and it turns out with a good CRT! That's about the only way to get the original white CRT these days, or even the green substitute, which is acceptable.

That is so rare to get a pilot with a good crt but would be nice to find one. I already have a 3kp1 green crt in it and have spares but a white one would be great.

What if you put a red filter in front of the 3kp1?

Tried the filter but it's to dark.

Didn't know!

Hey guys,
Thanks for letting me know about the electrostatic deflection in the Sinclair TV's. I had no idea they used that at such a late date. Weren't the Sinclair's made in the late 70's? Anyway, thanks again that helps me understand what your trying to do Timmy. When you get it working I hope you give some info on the modifications.

Thanks Guys,

Dennis

Other Tubes ?

Guys,
One other thing I would appreciate knowing. Are their any other examples of electrostatic deflection used in more modern TV's ? Maybe other mini TV's or perhaps view finders, etc. ?

Thanks,

Dennis
