On Ebay there is basically this:
2xHigh End 8pin Octal Teflon Tube Socket For EL34 KT88 5AR4 274B GZ34 GZC8-T-N | eBay
and this type:
High End 8pin Octal Teflon Tube Socket For EL34 KT88 5AR4 274B GZ34 KT66 5881 x2 | eBay
If anyone has an idea about wish one to recommend, please do 🙂

A couple of years ago I used 9 pin teflon.
And then I got a pcb that fitted the pins wich made it more easy to solder the components.
Ask if there is a pcb for it.
Any way this one:
seems to have holes in the pins wich should make it easier to solder components.
Edit:I also like the Belton sockets

If you look closely at the pictures it's obvious that it's not the same type of
construction and I'm not quite sure about if the first one is more like a
"bullet plug" in reverse (sort of). And if that actually could be a good thing.

I have footprints for these if anyone needs, ive used them, but Belton is better price/quality. and at 2 euro each a real bargain.
The nuts on the pins tend to loosen and the pins start coming loose. You can buy little round PCB boards that fit over the pins, and thereby solder the pins in place. The fixed-pin types are better but still a pain, IMO. I used to use these a lot but eventually found them annoying to use and too expensive. You can get perfectly good octal sockets for far less.

I think that's just an artifact of reflection in the pic. I have never seen them with hollow pins.
Morgan Jones discusses PTFE sockets and others starting on page 286 in his third addition of Valve Amplifiers. He seems to like them. Small cost compared to good transformers.
Well I finally bought the "VT8-ST Belton Octal socket" so...😎
I had the opportunity to buy one of the two teflon sockets in Europe. That's the
one I haven't tried before (bullet plug,sort of)and the other one became
ridiculously expensive when adding VAT and VAT handling fee's (they are nice though).

According to that same chapter in Morgan Jones' book, ceramic is almost as good an insulator as Teflon, and measurably better than plastic, micalex, etc.
If you use a pcb on Teflon sockets, aren’t you losing the advantage of the Teflon’s properties? All you are doing is putting pcb in parallel to the Teflon
the issue i have with china ceramic sockets is that i got a lot of broken center locator pins on my tubes....
The ones i posted pics are not Chinese.
These are made in USA by AMPHENOL, (in case anyone needs some, i can spare a small quantity, pm me)
