Tube swap from Med Res to Standard?

Paperboy isn't... You need to measure the resistance of the yoke windings. If they are incompatible (which I suspect they will be) then you'll have to try swapping the yoke.

Are you sure the tube is the problem?
 
usually when a tube was used for medium res it has a special yoke.

I know you can't put a standard 15khz yoke with 15khz signal and then try and put a 23khz med res signal on that yoke but not sure if you can do it the other way around.
 
Why waste a medium res tube?

Dim display?? Have you tried to cap it? I've brought a couple back already with a rejuvenation.
 
Medium res tubes also usually have a finer pitch. You can use the med res tube with a standard res chassis/yoke combination but going the other way can lead to a fuzzy pic.

Personally, I would save the med res tube for a med res game. Put the standard res tube on a rejuvenator and test it out, it likely has a ton of life left in it.
 
thanks for all the replies!
I guess I am not certain about the tube being the problem. I have never seen this issue before so I don't know. It is SO dim and no adjustments seem to help. Know of any rejuvenators in the North GA area?

As to wasting the med res tube... I have had this laying around for a few years and I just don't have(or know of) any other med res games in need.

I would hate to mess a working tube though by yoke swapping into unknown territory. I guess I will look for a rejuvenator or replacement std res tube.
 
the tubes typically used in paperboy are standard res. The yoke and chassis determine the resolution. A 19VLTP22 or 19VMKP22 are what you need if it's a Wells medium res chassis in the paperboy.
