The elusive Indextron

[Scott_Est]

No underlined links on my screen and I don't use any Adblock or similar programs.

I want to say once more big thanks to Jhalphen, who sent the full service manual for CKC021 viewfinder.

To fully analyse the schematics I need to print it out and glue these sheets together. But at first glance it is indeed quite strange system for me. This north-eastern corner in Europe we had 3-gun color-CRTs from the beginning of colour television introduction. I read that maybe England and other western countries had indexing-type TVs, but not sure about it. Though, one Russian portable color-TV set has one-beam electron gun, but creating colours to screen is done by two charged thin-wire layers between screen and the gun, that type of CRT is called chromatron.

I won't do anything to VF before I fully understand its "soul" and also I purchased a old and faulty, but reliable soviet era oscilloscope to make thing a lot easier. (Fault - scope has no horizontal deflection, but it easy to fix this.)

And have two more questions.

First: whitch is newer/modern VF, CKC021 or CKC030?
And second: what type of CRT is used in Panasonic CT-101A? Size is same 1,5 inch color CRT, but other information is controversial. One source said that it has 3 beam gun, other - 1 beam indextron(?).

Thanks
