Looks like a Wells Gardner k4600

You have picrures of the burned up ones?

SOLVED! BAD flyback. Unfortunately the malfunctioning flyback was new out of the box and I made the assumption that it couldn't be the problem,..lesson learned. Also, my normal flyback testing procedures (HV probe, HR Diemen flyback tester, and ring tester) did not catch this type of issue...

I've narrowed it down to either a flyback, neckboard socket, or neck board. The flyback I had in there was brand new and assumed it was fine, but when I swapped it out with a neckboard and flyback (older one with the white knobs) I had in inventory, I have no more jumpiness or wiggly lines. I'm...

Replaced the battery. 9.1vdc B+ reads 119. I did double check all the components around the power supply, including the filter cap and the Voltage regulator. Checked all the components around the oscillating circuit. Swapped out IC1 and IC2 I worked on a TV several months ago with something...

Should be able to see it now.

K7000 19" - Replaced all e-caps - new flyback - Tested this chassis on a different tube and yoke...same issue - Tested all pots Symptom: Jumpy screen and wiggly lines Outside of the upside down picture and purity issues (I'll fix those later), what could be causing this?

Hope this helps someone else Had a Galaxian with an old Wells Gardner k4500 monitor (original for the game). To install a k4900, I had to re-wire the monitor connector since there wasn't one of those small adapter PCB. Below is the original mapping and change needed to connect to a k4900 (or...

The next one I’ll give the wrong answer and you all can give me grief

K7000 25" Arcade Parts and Repair have these kits

Yep! @pat9000 and @mecha right... it's a Nanao MS9-29SU Did a little more digging, but got it. Thanks for driving me in the right direction !!!!

Need some help identifying this monitor. It looks to be some Sanwa model, but can't find any labels

I don't *THINK* the width cap (C312) or S-correction capacitor (C366) maybe the culprit, if you have compression on the right side. I think it maybe the linearity coil. If it was me working on it (YMMV): 1. I'd desolder the linearity coil and make sure it has no breaks in the actual coil or...

Good find! Odd it shorted and not burn open

Agree on the dot pitch and the yoke swap. Looking at the data sheet for both tubes, the dot pitch is very close. 19vJTP22 (k4600) - 0.032in (0.82mm) 19vMJP22 - 0.032in (0.81mm)

I am wondering what the original, stock monitor was for Crusin' USA. I followed a few threads here that seem to point to either/or U5000 or k7500, but wonder if there was a specific version of the monitor (different frame). A little background of what I'm trying to resolve… Someone local here...

Bought one

I'd be interested in what you come up with on the NTSC experiment. If I have time, I'd like to try in on one of my test rigs. Another question, I had a Sanyo 20EZ with a burn-free tube and electric guns still showing in the "green" on my tester. But, the guy that bought it from me said it was...

Thanks Chad! Keep these coming... All of the monitor experts! Few questions that have been pulling at me for years…. 1. Specs show that you can put both RGB AND Composite (NTSC) to the k7000. I'm assuming this has something to do with the P7 connector and the uPC1397C that supports teletext...

Looks like the focus wire isn’t plugged in the neckboard socket
