Help with k7000 hookup

So received @nimr0d 's k7000 yesterday did a quick check and surprisingly no other caps were installed backwards. Spent about 45 mins on it this morning doing some quick checks on the power and horizontal section and I noticed the horizontal coil was turned almost completely out of the coil, enough so it seems it was stopping the horizontal section from even working, further proof it was never tested. So adjusted that back to how it should. The color pots where all different crazy adjustments, thats why your colors were not right, your tube is probably just fine. Further proof it was never tested. They were all gunked up and hard to turn ao got some deoxit on them and got them all straightened it out. Fired her up and shes looking good with a few flyback and control pad adjustments. However there is still a horizontal width problem, might just be a width cap issue etc, adjusting the horizontal coil seems to do diddly but I will get her figured out later today or tomorrow when I get time. This tube is only about a 7/10 I actually had to rejuvenate it, it had almost no green but its been 2 weeks and the rejuve is holding strong always nice to see when they take. It also has minor convergence issues but the rings will fall apart if i tried to adjust it, so as good as she gets. This chassis will look excellent on a good tube.

Also, Fuck Patrick Scott Patterson.

Actual hero! Thank you for getting nimr0d sorted correctly!
 
All done and looking good. Someone had def pissed with either c69 and c36, i believe the 6126pf is correct but the 1026 I believe was what was stopping the width coil from having any adjustment, so I just stole them from another k7000 from the shelf thats waiting to rebuilt. Explains why they had the width coil spun almost all the way out. One was mounted on the bottom I think there was some revisions where that was correct but out of the 10 I have on the shelf none were that revision lol. Anyways width is good now and have full width adjustment from the coil if needed. Going to let it burn in rest of today and tonight( its already been running all weekend with no issues) @nimr0d i sent you a text and a video of it working.

Amazing work. Thank you again so much for unf***ing this. My kids will be eternally grateful to be able to play this game again after almost 5 months!
 
And it's back! 100% working and thank you so much to @JukeboxJon for his help. I had a little trouble with the isolation ground when I reinstalled it and he was cool enough to talk me through it at 9pm in the evening! (Maybe I shouldn't tell people he did that, everyone will except such service then!)
 
Yeah I'm kinda curious what was going on there basically in his cab someone ran a ground from the monitor frame of his k7000, to the main field ground into the cabinet and it appears its was causing the chassis to power down and only work for a few mins possibly making it go into shutdown. Normally I would not think a ground to the frame could cause issues as long as it was coming from the secondary side of the ISO. Maybe someone else here has some in sight I thought grounding the frame to the main field ground kinda nulls the whole point of using an Isolation Transformer. Hard to tell someone had also done some splicing on the 110 wires near the transformer too so.

Post a picture of the tube lol! From the picture i seen it look liked you had a really nice and bright tube thats lucky, a lot of k7000 tubes are very tired these days lol.

I think most or all cabs built with K7000s from the factory came with a ground wire attached to the monitor frame with a screw. It's weird if that caused a shutdown after being on a few minutes. If there was a wiring problem, I would think it would cause a short immediately. One issue I've encountered with that ground wire to the frame is that sometimes it may cause an interference or wavy picture, but that's usually because of a going bad power supply or poor wiring.

Yeah but they also moved it like they did some kind of a splice job and moved the ground to the main field ground post, usually i thought the ground to the monitor frame was grounded to the secondary side of the monitor iso transformer. Oh well its working like i said though they did other splicing too im not sure why. Will have to look at the nba jam i have in the shop and see how the frame is grounded on it.

I agree. Without being there and seeing it, who knows what kind of operator hack was done to it. But hey, if it's working, it's working .
