What are the best tube sockets available and is it a worthwhile improvement to make to a power amp?

One of my amps has one that is a tiny bit loose; only noticeable on the rare occasion that I move the amp from a shelf to the amp stands.

I see that Bakelite, ceramic, glass fiber filled, Teflon machined, PTFE composite, phenolic are available.

Which one would you recommend, better yet: which type would you buy for your equipment?

Thanks.

I would re-torque the connectors on the current sockets first.

depending how buried, replacing sockets can be a pita.

+1

Its the quality of the contacts that is important - surface area, clamping pressure + Oxide cleaned off.

Normally tube sockets will last as long as the equipment itself especially if they were made from ceramic material. Tube sockets wear and tear issues will depend on how often you retube. People who are into tube rolling will tends to have tube sockets wear and tear issues. If the tube sockets in your unit are made from bakelite material perhaps it's time to upgrade to ceramic as they hold much better from wear and tear over time.

Stay away from anything made in China, the variability in the metallurgy in its ability to keep shape and tension is not good.

If you truly want the best sockets you should try to seek out NOS American types such as cinch. Otherwise, Belton brand are a good compromise.

Good luck.

Don’t use the PTFE comp as they have no means of re-tensioning the pin sockets. Over time they become loose and some of the pins don’t make contact. I learned the hard way!

I replaced them with good old Beltons which are quite good. Great contact integrity. I think Jim McShane uses them in his Citation rebuilds.

I got some QQQ phenolics awhile ago and they look promising.

What type of socket? There are differences such as hole size and fastener spacing. Without that info we're just guessing.

If its an octal or novar any vintage inexpensive socket (that fits the hole preps!) such as Amphenal will be as good or better than any new production sockets.
