I have a WG 19K7610 monitor (thick neck) have a question about the neck. Typically, with G07 and earlier WG monitors, there is a plastic "boot" that covers the end of the neck, including the glass tip, and protects the pins from moving. This 7610 monitor seems to have a black boot over the pins, but it doesn't cover the end of the protruding glass at the tip of the neck. Is that normal for a 19K7610 thick neck monitor?

While I have your attention, I also have a chassis for a K7000 thin neck that has an additional, small "box" sitting above the flyback and also has a wiring going to the anode. What is that?

Can we see a pic?

Sounds like you either have a Zenith K7000A (made by Zenith instead of Wells-Gardner, it's a direct swap for the WG K7000) or you have a CRT brightener installed on your chassis (a device that kind of "boosts" the voltage to the tube to get a brighter pic, usually used on gun games). Again, we'd need to see a pic...

Thanks for the info and I will post pics of both.

As for the "box", I am thinking maybe the later since it has a WG sticker on it. The chassis has a handwritten "K7901" on it, but the WG part number on that "box" also says 7901, so that seems to match.

The "box" if different than other pics I found about this topic on KLOV.

Not necessarily. I have seen Zenith K7000A's on them with WG stickers. I think WG used them during production to make up a shortage of actual WG chassis back in the day...
 
Here are pics of the WG K7610 monitor neck and WG K7901 chassis with that "box".

I did compare the K7901 chassis to an earlier K7000 chassis and there are some subtle differences, such as the direction the degaussing coil connectors face and an additional copy of parts above the flyback (one black "can" can be seen in the chassis picture above the flyback and just to the left of the red anode cord).

the pins look fine maybe clean them a little.

that is a K7000a if you put a regular K7000 on it you will need to swap the neck boards

I don't recall seeing a monitor before where the glass was exposed like that on the end. Are you saying the tube or chassis is a 7000A?

As for the chassis and neck boards, please be more specific. My understanding is a K7000 chassis is compatible with all K7000 tubes, except for needing either a thin or thick socket on the neckboard to match the respective tube? Did you mean something else?

the chassis is a K7000a.

all monitors are like that on the neck that is where they seal the tube shut.
it is fine that way with or without the plastic key for the neck board.

if you change to a regular WG K7000 you will have to swap the neck boards as all of them were the skinny neck.

That is a Zenith made K7000. Otherwise known as the 'k7000a'

Scott, your understanding is correct. Provided that you have a neckboard that fits, you can swap the k7xxxa chassis with any other k7xxx chassis and you should be fine. If the neck boards aren't the same socket size, then you can keep the neckboards with the tubes and swap just the main pcbs of the chassis - they're plug and play with each other.

As to WHY the Zenith made flyback has the extra pieces - who knows? It certainly didn't make it any more reliable, that's for sure.

If you have a working k7000a chassis in your possession, get it installed on a game and sell it ASAP - get it out of your life before it fails. There's no replacement for that flyback, so when she goes, your only option is to drop in a k7xxx or get a import universal chassis from Alva.
 
Thanks for the clarification, gentlemen. That makes a lot more sense as I wasn't familiar with the K7000A. This is the only K7000A monitor (tube and chassis) I have (have ever had) and it presently has issues with focus and an excessive amount of blue (it might be the tube, but I have no way to know for sure). The only other K7000 chassis I have was tested earlier today and needs a new flyback (quite a light show). The way you describe the K7000A, it sounds like I should sell this chassis for parts (the working flyback) or trade for a regular K7000 chassis. Thanks for saying the flybacks aren't the same as a regular K7000 since I (incorrectly) assumed they were.

BTW, for clarification purposes, the monitor tube shown in the pics is not the same as this K7000A chassis was on (thick neck tube, thin neck K7000A neck board). Both of the tubes (thick neck as pictured above, and thin neck the K7000A chassis was on) have no burn-in, so my intent is to save them both by using regular K7000 chassis.

If you have focus issues with that K7000a, then your fly is likely on its way out anyway. Dump it quick.
Thanks for the update. I ended-up with a second K7000A chassis, so anyone need any goofy parts from these?

I also came across one of the "voltage divider" (or whatever that was called) K7000 chassis with the small box to be used for gun games. I will test it as is, but am thinking of pulling the voltage divider off if it's not needed (I don't own any gun games).
