Samsung A68QCP891X001 chassis is suitable?

[Bjt]

Hi, All

I need some help for crt Samsung A68QCP891X001 Flat tube which chassis is suitable? I have a well-functioning sanwa 31s. Or just only the C3129D chassis is useful?

I have a burn-in flat tube from Toshiba as a possible donor yoke.

If anyone has experience with this and has tips, I would love to hear them.

Thanks b t

since the tube is dual focus I guess it's either the WeiYa C3129D or mod a toshiba trisync chassis:

Would be cool if you can do a yoke swap. Maybe Dewman knows?

But, yeah, AFAIK the only "known" (public) solution is mod one of the Toshiba chassis or get a 3129/Rodotron 666 or equivalent.

I have a few of these, it's single focus. Is this tube from a TV or from an arcade monitor? What yoke is on it?

I have tried swapping a few different yokes on these and the best result I got was with a Toshiba PF yoke (Toshiba tube), but it took hours of work and adding many magnets to get an acceptable result, and even then the purity is not perfect. I stopped buying TVs with these for swaps and started looking for ones with Matsushita flat tubes.
