Which of these tubes is more compatible with a K7000 chassis

I have a K7000 chassis and yoke from a 13" monitor and three 13" TV's ready to put a working monitor together

Which of these three tubes would be more ideal to start with?

A34AGT13X78

H- 5.5

V - 15.4

A34EAE01X

H - 7.7

V - 12.2

370KSB22

H- 6.3

V - 14.1

I'm off the next few days and anxious to get started on this, so any help would be great

Thanks again
 
These are measurements I got from 2 tubes I was puzzling out if they would be interchangeable or not - both native K7000 tubes - and they were interchangeable.

K7191 tube - red/blue = 1.8, yellow/green = 5.8

k7193 tube - red/blue - 1.8, yellow green = 10.3

From this site, all confirmed compatible replacements are around 1.3ohm - 3.6ohm horizontal.

That said, you might be out of spec on your potential donors.
 
If you are swapping the yoke no need to measure what's there.

They are all CR-31 (thin neck/10 pin) so make sure that is compatible with the chassis neck board you have for your K7000

If you are not swapping yokes, they will all probably work but would try as suggested 1 then 3 then 2
 
Yeah I am def swapping yokes, I made sure to get both when I bought them so the chassis and yoke would match

Thanks for the suggestions everyone I'll start with the A34AGT13X78 first
 
yeah they are..putting in a pacman cabaret

ok, I assumed they were all 13" - thanks for the heads up
 
Just as an FYI, the numbers in the tube label usually indicate the size of the tube in centimeters. 34cm would indicate a 13" tube.

That last one, at 37, that's more like 15"

They're all the same, 14" tubes with a 13" screen diagonal. The japanese designation refers to the whole tube face (37cm = 14") and the worldwide designations refer to the 13" screen (34cm).
 
Thanks everyone, got the 1st tube installed and getting a
picture...had a few questions.

Why would the imaged be chopped off like that and not centered?



I also am having issues with a pulsing flashing of the screen, like a tick tick tick tick...you can see it in the pics
 
Here is the original tube information that came with the chassis originally..




Yoke is on this one now...#1 in the my first post

 
wonder if I needed these piece from the arcade chassis as well? Seller didn't include it

I had to re-use these from the TV and paid attention to line them back up according to the paint mark. But I am pretty sure it's going to need some adjustment on this set up. Yoke is from the chassis and that's from the TV.

Is this a pacman pcb or a 60-in-1 with pacman? if 60-in-1 could be cga/vga dip switch. Or could be a sync issue.
