You could connect it to a LCD monitor and see what resolution it's outputting.

Re: Astro city Monitor problem

could be a pot but unlikely unless someone has physically broken it- more likely is vertical deflection ic or cap failure or bad solder joint

Re: Tosh A68KJU96X Nanao MS8 -> MS9 swap

it will work but yoke connectors are different, ms9 uses 2 x 2 pin connectors and one of those has a narrower gauge for the vertical header

Re: Nanao Ms9 on A68LBT696X

the tube is not the issue but the yoke is the ms2930 yoke is around 0.195mh horizontal inductance whereas the ms9-29 is around 0.300mh, it will run but i would expect the HOT to be driven hard and geometry issues for example if you run a toshiba pb 6643 on a ms2930 tube/yoke it will short the HOT wi...

Re: Demag circuit not working on NAC MS9-29A

demag fault can only be wiring or ptc, i doubt its the ptc so wiring is most likely

Re: Adjusting B+ on Nanao MS9-29

don't touch b+ when swapping between ms8-29 and ms9-29 tubes, its not required as the ms9 has so many adjustments it can handle the slight difference in the yoke
