Has anyone ever seen these sockets for the 6C33C?
fiogf49gjkf0d
New here, but I thought I would continue my 5+ year search for another pair of these sockets.  I have all the parts to build a 6C33C OTL using 4 tubes and would like to find another pair of these.  I have one pair that I happened upon late one night 5+ years ago and have not seen any others all that time....and I have been actively searching.  Thanks much and sorry if this is not the place to post this.

Indeed, a rare socket.

I do not think that it is socket different. The socket is invisible and it appears rather a standard Russian ceramic socket. What is unusual is that the tube has a harness that typically used for permitting the tube to work upside down and under dynamic stress. I never seen it before and that is certainly makes is very fascinating. What is interesting would be to guess who the hell used the tube like this? The type of the making depicted on your picture suggest that it is not some kind of boutique hi-fi shop but rather a Russian industrial production from 60s. That would be easy to get that your socket was used in MIG jet fighter (where the tube come from) but on MIG it was no spring loading.

Prom engineering perspective the spring loading would be better and it is possible that your socket is some kind of modification used on Russian MIG. I do not think that this socket is practical on Hi-Fi environment but it would not hurt as well.  If you make the socket like this and make the spring cold-plated then you will be able to sell them to audio people who will swear that this golden socket will be able to convert sound of Boston Symphony Hall into the sound of Vienna Musikverein…

The search goes on

Yes, the harness or hold-down is the unique feature.  The actual socket is normal run of the mill stuff.  I've contacted many MIG parts suppliers to no avail.  I just happen to be cruising eBay one night when these popped up and I snagged them.  They remind me of the Android caricature.  I'll continue my search and let you know if I find a stash of them.  Cheers, Dennis.

How much efforts you would spend for go after it?
fiogf49gjkf0d
Dennis, you for sure might contact “MIG parts suppliers” and “continue your search” but why would you need to do it? That is certainly not my busses and you can do whatever you want but to dinging into the history and discovering who and why made that socket is not what audio is all about.

Audio sculpture
fiogf49gjkf0d
My other love and career has been as a metal sculpture so I like to mix the two.  It gives me great pleasure to see cool looking audio while ensuring that it sounds a good as possible to my ear.  Using 4 of these tubes in my next build, I would like to have all four tubes in these tie-downs (whatever they are called)  Going to all this trouble is perplexing to some but a mission to me.  Here is a picture of a Pete Millett Low-Mu preamp I just completed.  Electrical engineer friends of mine ask why I go to all the trouble and all I can say is, "it looks cool."

Had to resize the pic

The first attachment was too big.  This one should work.
