Hi
I have a question about this pot on the flyback: If I adjust it to 60 hz, than games like mortal kombat are cut off at the bottom (it runs 53 hz) and if I adjust this pot to 53 hz, than when in 60 hz resolution, there is a squeeze at the upper lines. Is there possibility to adjust it, that 50 and 60 hz resolutions will display properly? It would be great as I use a mame cabinet with soft15khz and I change games and resolutions a lot.

This monitor was designed for use with one game only in a commercial use. You set it once for the installed game. It was never meant nor designed to be changing all the time like in a MAME setup

That is exactly what I thought. It is strange feature though, because 8liners chassis didn't have any problem with that.

The k7000 was designed in 1985. The Jen Shinn and Wei-ya chassis sold by 8liners are modern designs from 2000.

I didn't know they are this old, thanks for info. Anyway it is not a big problem.
I was wondering also if there are ways to obtain more vibrant colours on my K7000. I know it is very old, but in comparison to what can produce my 12 year old Samsung tv in scart rgb mode, it looks weak. I have made capkit and I use ultimarc video amplifier and everything looks ok, but I would like to "boost" it a little. Is it possible?

Sorry to reply to an old post, but nobody answered him. You can get the tube "rejuvenated" at a local tv repair shop. (heard people say it is likely $25-$70) This helps the emmisions of the guns in your tube from what I have read. It can also find other faults when they use the device to check your tube out and can fix some of the problems like certain types of "shorts".
I wanted to get this done on a K7000 I just got in an MK1 cabinet, but figured I'd go the whole 9-yards and went ahead and bought a rejuvenator off of Ebay so I can learn to do it and have it around for future use. I got a great deal on one for only $75 with shipping ($65 after a $10 Ebay bucks rebate I earned). So now hopefully I can bring new life back to the old monitor.
Take notice though, some people say there are chances of damaging a tube beyond repair with this process. More people seem to see vast improvements than catastrophic failure, though.

just a thought,
you could wire up 2 pots (matched to the 50/60hz pot) and remove the original pot... wire up a toggle switch to switch between an adjusted 53 hz pot and another adjusted to 60hz
