Monitor Identification
« on: December 27, 2017, 03:50:33 pm »
I can't seem to figure out what I have.  The cabinet I picked up has been rebuilt with a X-Arcade CP, so I'm not sure everything else in here is original, but it was/is a High Impact Football cabinet.  Attached are pics of the monitor, tube, chassis.  Anyone able to tell from these?  It's old, for sure.  Appreciate any feedback.

Thank you!  Been trying to identify it but couldn't find a match.  Appreciate it! 

Now if my picture is shifted to the right, do you know if there is a Horizontal Position potentiometer?  I can't seem to locate one, and don't see one in the manual.  Do I just adjust the Horizontal Width Coil to make it fit on the viewable screen?  Other solutions?

The tube is from a Hantarex MTC9000 but the yoke has been swapped.

That was one of the reasons I couldn't identify it.  Was looking through Hantarex monitors.  But just the tube is Hantarex.  :)

Ken, I've been reading through lots of your older posts regarding this monitor on some other forum threads.  Is it possible I do not have the Horizontal Centering Potentiometer on mine?

The last page of this K4600 service manual shows the adjustments:

You're the man.  I will take a look and try to remedy tonight.  Really appreciate it.  Hopefully, you've saved me from dismounting and bringing to a repair guy for $85 per hour to troubleshoot and turn a little knob.  :)

I get some off colors in the bottom left and top right corners.  Hoping I can just use a degaussing wand to fix that, but do you think it's perhaps something else that needs fixing?  Caps?  I'd really rather not put a new cap kit in, but maybe down the line.

A degaussing coil is much better than a whimpy wand.

Right, but where can I find one?

Here are a few pics of my monitor, one at the same angle as the schematic from the last page of the manual.  Looks like I have no Horizontal Video Position, right?

Yes, you do have the horiz and vertical adjustment jumpers installed.

But no potentiometer that I can find.

The horizontal hold and vertical hold controls are on the "hor/ver" board (a.k.a. the "X/Y" board).

Thanks, but still looking for Horizontal Position (not the hold pots).

There isn't a POT there is only a jumper.  If that isn't getting your image where it belongs then you may have a problem with the horizontal frequency.  There is a POT on the X/Y card to adjust hold as well as a L351 coil on the X/Y board.  Again, as Ken indicated, check the last page of the service manual items #6,#7,#9.
