I saw a 25" sharp tv on craigslist today for 20 bucks and thought I'd pick it up just to see if it would be compatible. opened her up and its an A63LAT80X tube which shows 6.3 heater voltage and a cr 23 neck. I measured a yoke in one of my k7000 chasis and it showed 1.9 ohms on the red and blue and 6.3 on the yellow and green. The donor tube shows 1.6 ohms on red and blue and 7.6 ohms on the yellow and green. I'm assuming this is close enough for a swap but thought I would ask here to see what the more experianced has to say as I just started working on this stuff. If so this will be great for a much as I like battle toads I'm not to found of it being burned into a screen on my mk2 lol.

What's the model number of that Sanyo TV?

Yep, should be good to go!
 
Actually I was wrong it was a sharp 25". I'll post the model details tonight when I get home. I was Quite suprised at how many components on its board that were identical to my K7000. I will be busting out the desoldering gun on it and creating a stock of test parts.
 
thats pterry close. Run it and see what you get. Let us know the model # of the tv so in the future other guys csan hunt that same set at goodwill, etc.
 
I found a couple of cheap Sharp 25s on CL local to me.
I'm hoping that a 25H-S100 is going to work in a tube swap for K7000 25" tubes.
I have a pair out of an Xmen 6P with some of the worse burn I've ever seen, but they otherwise work fine.

ok I hooked it up and it works fine. The picture is bigger compared to my other tube. Vertical can be adjusted just fine but I will have to change the width cap to get the horizonal done as I turned my coil all the way down. It helped but not enough. Also the green and yellow wires had to be swapped as the picture was upside down and reversed using the normal red blue green yellow pattern. The only thing is that the picture in the middle at the top seems to be sagging. 50/60 is cranked all the way down to help and sync is on pin 10. This chasis was giving me problems at the top anyways though. Has a new flyback and cap kit. Had to do major repair work on the bottom in the usual bad areas so thats my guess where the problem lies. None the less the picture is bright and clear.

looking pretty sweet.

be sure to look at it without the TV housing as they will hide the picture a little.
put it in the K7000 frame before you go messing with the width to much.

man that looks really nice.

Just to be sure, I'm to measure the resistance betwen the red and blue
then I measure between yellow and green on the connecter coming off of the yoke?

I just picked up a similar Samsung from 2000 and i'm hoping that it's the same tube.
 
Yep blue and red - then yellow and green. The connector was smaller so I had to de-pin the wires to plug into my chassis.
 
OIC, I'm going to crack open that TV now to see if the tube matches.

I got readings of 1.3 R/B and 8.2 G/Y... going to cut the connector off and crimp a connectors for my chassis.

UPDATE:

Still need to hook up the degauss cause it was a different sized connector. I guess the thing to do is to cut all of the connectors off of the old tube.

The tube was a A63AFW36X

Sweet looks good. Like I said earlier. You can just de-pin or crack the molecular connector on the TVs degaussing wires and slide the crimped ends on to your chassis post. I just need to stock up on these old TVs I guess before they get too expensive.
 
after your post, I did a CL search and found two immediately. This Sharp model number 25N-M100 25" TV was FREE and worked great. The year listed was 2000. The other i'm picking up in another day or two is from 1996. So between your first 1993 one and this late model 25" I think that most of the Sharp 25's will work in WG K7000's

I'll get to taking it out of the case and mounted in the K7000 frame tonight. Then I can digg around the width coil issues that this tube also has.

Here's the before tube's burn in.

and then the transplanted TV tube...

I changed out the .39 uf C38 width coil for a .47 uf cap and it seemed to put it nicely in range to adjust with the width coil. I'm going to have to start a perm search for this model of TV as I have a mess of 25" K7000s with various levels of burn in.
This is just really exciting as I think there's like 7-10 years of Sharp 25" tubes that may work for the swap of this common monitor.

I just found another Sharp that has similar readings so is compatible. I'll finish wiring it up later tonight. I did a little different this time as I decided to completely transplant the degauss coil and ground strap also. The TV ones don't seem as good to me and it also lets me retain the degauss connector vs cutting it and transplanting it.

Sharp Model# 25H-S100 from 1996
 
you would understand correctly, I do it all the time and they look great!

is that simply cause it's kind of a bitch to remove the rings without breaking them most of the time? :p

I've done a swap on a K7500 so no way around it, I had to swap yokes. wound up trashing the rings though, cause they were glued like whoa to the neck.
