Don't you mean Han Solo? We used to pretend that fluorescent tubes were light sabers... Now that I found a trap (not the original ) , and as mentioned, once I pull out and finish the CTC-90, it will be time to play with this monster, and first off, trying to work out how to safely (temp?) mount the CRT for the testing.

the closest thing I can find, so far is a 8KP4 at the ETF, same general wiring and biasing, & it won't roll off the table, the only major dif, is electrostatic vs magnetic focus, & that most likely wont matter for repair.

Ready Ion control... Yes that is silicon on the pin-cap. it was damaged over the years with all the moving, but still checks out very strong.

When I do ever get this working, is to try and build a larger size cabinet for it, out of wood mostly, birch plywood, finished to match the CRT surround I have.
The electronics / CRT chamber on top, will have an clear plexyglass top, so the guts can be seen from above when running, below it will be the speaker chamber, for the 8 inch Jensen that was with it, which still seems to be good. I don't know how tall it will be when all is said and done, will have to work that out later. I WILL BE putting cooling fans in it though!

test CRT came today, a used 8YP4 ( from ETF)
https://imgur.com/5rxArRx https://imgur.com/BjSCvw5 https://imgur.com/dBZlbdD cute little thing! minor scratches and screen burn, worth it, over all. NOW I got to come up with some sort of socket to hook up to it. the socket to my 12lp4 is damaged, ad i was going to replace it anyway, I see out there that they had adapters to hook this sort of thing up to it, I could wire up a socket for the 8YP4 temp, but I am not sure what to get to start with. what do I look for that will plug on to this thing?

i know what it should look like.
bk-precision_cr-11 https://elektrotanya.com/PREVIEWS/38...r_sm.pdf_1.png i should be able to get that socket someplace ... edit, ALMOST, but not quite. the pins don't match up https://www.ebay.com/itm/Vintage-7-p...-/123774257767

Isn't that crt vastly different from what the set is supposed to use?

Once things are more or less stable with the chassis, and an enclosure is made for it, then I will switch to the 12lp4 for the final (permanent) repairs and restore. The test CRT is a bit more robust, and will take some abuse, and I don't want to risk the 12lp4 until I can get a stable picture on the thing. The CRT wires on the chassis are in crappy shape ( 5 of them ) and I will be replacing them anyway, so I am planning to run them from the chassis to a terminal block, so I can easily swap out socket types when needed.

I think I may have the exact adapter you need from an old test jig in my knick knacks... Yama if I find it your welcome to it for postage cost.

I'd much prefer to have some kind of socket for it, but if nothing can be found, as a last resort, I can prob hunt down a tube socket that has generally the same size pin clips, pull them out and solder wires to that and hook those to the CRT, and hold them in with heat shrink tubing.

And so it starts...
https://imgur.com/bucYKCw Replace the 40UF with 50uf, and 80UF with 80 or 100UF, ( wont matter much.) but what I am wondering is, the 5U4GG, https://imgur.com/OFeDbkt not even sure if they are any good or not, replace them with a hefty diodes, ( keeping the heaters hooked up so they glow ) or go with the orig tube RECT? hmmm
