Monitor question

[mr_doles]

This week I was able to get my hands on a lot of arcade parts from a building getting torn down.  Gutted some smashed up cabs for parts that I need to go through and test.  I got 3 monitors that were in a box, debating on going back to get the other one .  After researching I believe that 2 of them are U5000 monitors but wanted to make sure.  I attached a picture of the label on the box.  The other box had a brand new (I think as the plastic cover was still on the tube) 19" monitor in it.  The box was hand written with Crystal 19" w/o touchscreen.  Any clue on that one (my buddy took that one in his truck so I can not post a picture).  Is it worth it for me to go back and get the other U5000, a lot of people here don't seem to like them so I'm not sure I could sell it.  They all seem to be in good shape except one had some rust on the left hand side (and a lot of cobwebs), though I need to plug them up to see if they work.

Can't quite identify it from those pics.... no real pic of the main chassis.
Find a "Pxxx" number on the main chassis.
Or at the least a good pic of the main chassis.

The U5000's are good when they are working, it's when they fail that can be much more of a pain than the usual monitor when they fail.
And even though some are "switchable" between 15 and 25khz resolutions, they don't always like to cooperate when doing so.

Free..... I'd snatch them up in a heartbeat.... but then again, I don't mind working on them so much now.

Looks like P583?

[Kevin Mullins]

P583 is a neckboard number typically on a U3000.

What about the main chassis..... the big one ?

Almost looks like there is a third (small) board in that one pic of yours, curious what that is.

[mr_doles]

Just realized that was the neck board not the chassis...doh.  Got to try to flip it out to see that, will do that in the morning.

EDIT:  Just read your response, yes I did the neck board, whoops.

[mr_doles]

Does P655 sound better?

[mr_doles]

Here are pictures of the 3 boards.  Not the best quality its late.

Found this on a German website...
 P-655 25 kHz längsgeregeltem chassis with separate power supply and 2x AC input: 128V and 30V ca
Figure 1
Not sure what längsgeregeltem means and neither did google. 
I give up going to bed and letting the pros help.

Ah.... see that third little board is kinda crucial, it's a power supply.... makes me believe it's a medium resolution K8000.
Honestly, I don't see too many of those around.

These are 25" I presume.

[mr_doles]

Yes it is a 25" or at least that is what is says on the box.
I believe you are correct, after a little more digging I found
K8000 - p649 power board type - medium rez 25" 33" - P655 P657 P645 P648
though the powerboard I have says P104.
Why can't they make this easy, put K8000 somewhere on there if that is what it is.

Now I got to get a look at the other crystal monitor to get some info off of it.  Not sure when I can do that though.

[mr_doles]

Well here is when I am with the Wells Gardner monitors.  I did go back and get the third and these are the numbers I pulled from them.
Chassis P655 Model 25K8112
Chassis P657 Model 25k8112
Chassis P655 No sticker with model number
So I am guessing that these are all Wells Gardner K8000 monitors?

The other one was a Kristel C72259 (my buddy still has this one so I am going off of what he is telling me).
