6100 compatible tube, but 20"??

I found a tube in a yard sale tv - A51ABU10X. When I picked it up, I didn't notice it was a 20" set. I figured I found a dud, but today noticed that it looks like a 100deg tube, and I see from the BK list that it's a CR24.

I have a 6100 with greater than average burn. Would it be worth attempting a tube swap, IF the 20" tube ears will mount to the 6100 frame? Here's some pics and thanks for any advice.

If the neck is the same diameter you can get it to work, you may have to make an adaptor if the pinout is in a different order.....or you could open up the amplifone connector and move the wires around to suit. If the plastic part on the end of the tube doesn't fit you can removed it, you will need something to soften the glue first.
 
Cool, I guess I need to figure out how to compare the neck pinouts and verify that. I'll check the fit to a frame today.
 
I'm looking for a 6100 tube myself. What model tv did the tube come from?
 
No, I just noticed it looks flatter than the 90deg tube. Maybe it is? Can anyone confirm? Thanks..

Look at the number cast into the back of the tube. First 2 numbers will be the size. Then there will be a V. Numbers after the V will be the degree. Picture looks like it is a 20V110

Check the BK Precision tube setup chart for their CRT testers. Do both tubes use the same adapter? ;)

I think it would be better Joey to use a 90 degree tube than a 110 degree, as your early pics clearly show

At least there are documented cases of the 90 degree amplifones working in a wg6100 setup. They only complained about slight bowing at the sides

That tube looks too different, with multiple pins in the triangular area. Looks like a sony type tube, which uses incompatible voltages
 
Well, you don't know until you try. If it is a CR24 neck, and the proper heater voltage, then it will probably work. Try it. Worst case, you won't be able to converge it. It also won't fit in the frame without modifications, but just leave it mounted in the TV face for testing - if you can get it converged correctly, then you can worry about mounting it later.

..and we have a loser! I confirmed it's a 110deg tube. Need to hit the thrift stores this weekend and find more tubes..

Thanks everyone.
 
Dude, pull that socket off the end of the tube. When you do find a compatible tube, you will need that socket to replace the other one which will probably be incorrect.

And, of course, you should save the neckboard socket from the television. Those are kind of hard to come by, and required to build CR24 adapters for rejuvinators.

I'm also not 100% convinced that this tube won't work - sure, it's the wrong deflection angle, but it might not be too bad. It's possible to jam a 90 degree tube in a 6100 and have it usable, so I don't see why a 110 degree tube would be any worse. At least this one already has the right connector on it. It's still worth trying, if even to see how far off the convergence is.

True that! I've had a couple 6100 over the years with shot/corroded neck sockets. 110 degrees......I've never seen a 110 degree tube, didn't even know they made one at that angle. Talk about UNCOMMON!

It's the unicorn of tubes. Sounds like my kind of luck. You don't find the difficult, you find the near impossible....but it may not help the cause.
 
I found one of these last week. The neckboard was stuck on. I tried wiggling it and heard the hiss. That was when I noticed the weird socket. I destroyed the neckboard trying to take it off. Now the whole thing is trash.

Anyone know what the V means? Are there ever any other letters there besides a V? I guess there would have to be otherwise why put it there if it's the same every time?

i believe the V means vertices or vertex following the V is the degree of angle.
