I need to use a separate little circuit for one of my tube testers that plugs into a 7 pin mini tube socket and an wondering if something like that ever shows up? If not, how can I make one up since the tube is all glass. Normally on most any tube I would just take it apart and just use the bakelite base.

You mean like these?

Might also check Surplus Sales of Nebraska, I picked up some 7 pin socket plugs from them in the past. Also shows up online at auction, I can also check locally if you can't source them. Last set I bought from eBay the pins were corroded but cleaned up ok, used for a SS rectifier replacement in AVO CT160 testers.

Ed,
I have a used 7 pin plug, with a bit of the bakelite edge chipped off. It is still sturdy and perfectly functional. Yours for shipping cost, which is probably about $2.50

I had almost a hundred of them, NOS, but I sold them to Bill Turner to make his 1L6 adaptors.
