Just picked up a Track & Field - first arcade to own. Looks great next to the four pinball machines. I've been messing with the edge connector wiring attempting to fix a trackball issue on the game and BAM! Knocked my head off the neck of the tube and snapped it. POP! HISSSSSSSSsssssssssssss! Frown. Sad

The monitor was gorgeous. From what I can see on the stickers, it's an Electrohonme G07CBO (38-G07-904-00) with zero burn-in on the tube, which is marked 19VJTP22/19VMAP22.

Everything video was working great. Colors were nice. No artifacts of any mention. But now with a cracked neck, how do I proceed? What are the next steps? If anyone can help me out, that'd be great.

Your only next step is a replacement tube. That's a bummer dude! It happens to all of us, don't feel bad! I did it on my Pac-Man cabaret. Sad

Here's a good starting point:

Or... just find another monitor and start over.

Thanks, John! But UGH! I feel so stupid. Thing is, I rap my head coming out from under tables and desks ALL THE TIME! I think it's my glasses. You'd think I'd have learned by now the dimensions of my noggin. Apparently not. Just rapped it right off that thing. Knew exactly what I did. Can't be more angry with myself.

I've been doing some reading for a few hours (since I can't play it) and still learning the ins and outs of tube swapping. First, I need a tube with the same pinout (CR-23). Then, from what I've gathered so far, I can use the G07's yoke on the new replacement tube since I know the G07 chassis and yoke were fine before my accident.

But my biggest primary need is a 19" tube with a CR-23 socket, correct? If I go dumpster diving or sidewalk picking or thrift-store searching, this is what I need to begin, correct?

You need to find one with the correct socket and a close reading on the yoke winding resistance.

But if I use the same yoke, the need for the winding values goes away and is replaced with convergence issues, yes?

Potentially you could end up with convergence issues. You are better off leaving the yoke the same and just getting a tube with a close value.

The list of potential high ohm yokes seems to be shallow though, compared to the number of low ohm yokes out there. I don't want to end up with 10 broken tv's in my basement in the end Smiley

Here this is a shop local to me called Big Toys. I just had them rejuvinate a tube for me and they told me that they have a lot of tubes in stock. I'm sure they can ship one to you if they have the correct one.

G07's are alittle harder to find direct drop ins...  I just did one myself.

you have two options.
harvest a G07 from a junk machine you pick up cheap.
just dive in (got nothing to loose) and find a donor tv with a direct drop in tube.

3rd option gets ugly..
buy a working good g07 off ebay or seller (pricey)

Thanks for all the ideas. I managed to get the G07 out of the cabinet today. Got the machine hooked up to a CGA->VGA converter in the meantime so I can at least play it.

The monitor looked to have no burn or issues when in the cabinet beneath the smoked plexi, but in fact, it was in a Pac_Man, probably for quite some time as the burn is pretty noticeable. Still, the picture was great, nice and crisp. I hope to replace the tube soon. Doesn't look to be that difficult from the videos I've watched. Convergence just is something I haven't ever touched before (other than on rear-projection sets).

with the right drop in, you might not have to even mess with the convergence.

I did a swap recently and I shit you not..
just hooked up the chassis,, looked brand goddamn new.

Where did you find the replacement? Craigslist? Another user here? What are some good resources to find these things?

I don't know if this is a Pennsylvania law or not, but the Goodwill store here will no longer accept CRTs. (We also can't put them out on the curb either.) Too bad. I have to call recyclers to see if they have them if I'm to find anything apparently Sad
