Those Sencore universal connector adapters are great when you're working on a tube on the bench. A whole different story when you are trying to attach them overhead in a hanging projector by feel when you can't see all the pins.

The green tube I pulled from the 4600 had almost zero emmision with no shorts. I whacked it with "Auto restore" and emission now nicely centered on the good zone but when I was finished, I now have HK short

Back to the blue that is still in the projector.

Those clips could be replaced with pin sockets. Slip right over the tube leads. Something like 7405 in the .pdf would let you solder the wire in the end and insulate with heat shrink tubing. The tube pins are 0.040" in diameter.

Why not just get an old color TV CRT tube socket and clip to the leads on it? I've done that with an NEC socket so I don't need to pull the tube out completely in a PG, I haven't needed to do it yet with a Barco/Marquee.
I have those sockets if you want one. Without leads though, I'll pull it off an Ampro video output board...

The blue tube tested flat on the cutoff and emission even after three shots at auto restore. I had another blue mounted up but also low just not as bad. I whacked that one and got a little more life out of it so I pulled out the flat one and was installing the better one for now. I took a break and decided to look at the one I just took out. I hooked it back up to test it on the bench. I tried "Auto restore" a couple of more times with zero results so figuring I had nothing to loose whacked it with "manual restore 1" and no luck even after multiple attempts. Again, nothing to loose, I whacked it with "manual restore 2" which sends a goone load through it. I saw something I never saw before. There was a green glow coming from the area of G1 and then a bright green flash and the meter jumped up and I took my finger of the self destruct button.
I don't know what I burned off but right now the dead tube test about 90%. I think I'll slide that sucker back in and try it.  It will probably last a week before it Sugar Honey Ice Tea's the bed.

And you're just figuring that out
How much damage can you cause to a dead tube anyway. And just for you, I think the color with two different tubes looks great. I still think it will be much better for the projector to converge like tubes though. A quick and dirty setup looks great though.

Didn't even last a day and a half
Oh well, renewed incentive to prep three couplings for Thomas tubes. Must remember to order new fluid...
