So i'm doing a tube swap on my Ms Pac from an old zenith I found at a thrift store, and a few questions have arose. What are the connectors for coming from the yoke in the picture? I know they connect to the chassis, and I still have the original connectors from the old burnt tube to swap, but say I just needed a tube donor for an extra monitor frame I have..can I find those connectors if I didnt have the original tube to use for parts? Also, if I went with a new chassis from 8-liners or whatever, would they come with these connectors for the tube? Thanks for any advice, and if that didnt make sense, say something and i'll try to clarify.

points of interest: make sure the resistance on the yokes of both your original tube and the donor tube match. I don't follow this tube swap shit in great detail, but I'm led to believe that even if they match, you have to swap over the yoke and rings from the old tube to the new one.

your yoke connector will plug directly into your chassis. why? cause it's the same yoke, you're just changing tubes.

make note of your ring placements too -- converging from scratch is a bitch. :)

am I missing anything here?

Vertical and horizontal deflection. i.e. they control the horizontal and vertical position of the electron beam as it sweeps across the tube face.

So I really need to swap yokes? That sounds likea bitch! Can anyone else chime in on this subject?
 
Do some Googling, There is Plenty of information out there on it.
I Learned a lot by Googling. I learned how to change Tubes without asking one question.
No Offense, Not a Easy Thing But Can Be Done.
I Do It. And I am.
Butthead.

Here dude:

You need to ohm out the yokes. If they are very close then simply cut the connectors off the yokes and replace the connector in the new yoke.
If they aren't close then you need to do a yoke swap. Convergeance will need to be performed and that sucks but what helps is drawing a line straight across the magnets and measure how far from the end of the tube it sits. This will get you very close if not acceptable.

Convergeance probably only needs to be done if the yoke is swapped right? If the ohms on the donor tube are the same on my original ms pac tube then ill swap tubes for that. IF they aren't the same, ill most likely buy a new chassis from 8-liners. Do the new wei-yas come with a new horizontal/vertical deflection connector for the chassis pcb? I couldnt find that info on the site.

Convergence is only needed if yoke is swapped.
Every tube donor I've yanked out of a TV, I ohm'd out the donor tubes yoke and bought the appropriate chassis for it. Then I cut the old yokes connector off, cut the new donor tubes yoke wires off and then soldered on the old yokes connector.
Best place to buy is alvaamusement.com.
 
Measure both yokes, first on the red/blue wires (horizontal) then whatever the other two are (vertical). If they are close, say within an ohm or two on both readings, you're prob safe to use the one already on the tube. If they're way off, for example, 14 ohms (horiz) on the TV vs 3 on the orig monitor, then you'll have to swap the yoke.

Click the donor tv link on my sig, then look to the right, there's a tube swap guide I put in there. Its not perfect yet but that should hopefully explain everything.

Also - please send me the make/model of the TV you got, with the number of the tube it had inside at the least. If you do take yoke readings, send those as well so I can add it to the list.

BTW Orion3311 let me say that's awesome of you to take this database on.
At OP - to avoid any confusion, swapping yokes will only be necessary if the original chassis is used AND the new yoke doesn't Ohm out the same/close as the old.

thanks for pointing that out, I always wondered why you'd have to change the yoke if they read the same resistance. I'm not good at scrapping, so tube swaps probably aren't in my immediate future.
 
what's important in a coil is the number of windings and the working impedance. It's very difficult to measure these, but resistance varies with wire length and thus gives us a fair approximation. Since most CRT's are very similar, matching resistance works most of the time. BUT.... it is possible to get two yokes with idential resistance that don't swap nicely.
 
Orion, You ROCK!!!!

What a great site you have set up!

I don't know much about monitors, yokes, ohms, and such - but someone else (Oli) has been kind of coaching me with posts and emails.

I don't know what I was doing the first time I checked my Hanatarex yoke- I would guess I did not use my meter correctly and did not get any results. I think maybe the battery was going dead as well.

I took measurements today - still not sure what I was looking for ...but got 1.6 and 5.6 ohms....looking at your site tells me that I did not kill my yoke - and hopefully not my monitor.

Thanks!
