Hi,
I recently bought a working Precision 912 Tube tester. Upon trying to test miniture tubes for my T/O I discovered that the pin sockets just slide down inside the socket on the tester. They do not appear repairable. Does anyone know a source for these sockets ?

Any help appreciated

AES, tubesandmore.com, sells all kinds of 7 pin miniature tube sockets. For a tube tester use good quality.

Tom,

Although replacement might be the best course, I had good results in my attempt to tighten the 9/10-pin minature socket on my EICO tester. I repeatedly wedged a small jewelers screw driver between the metal connector and the surrounding plastic hole. Work your way all around each pin connector; the idea being to bend it slightly inward, back to a tight fit. Give it a try....you can always do a replacement.

Sounds a little crude, I know, but remember that all you're doing is reversing what's happened....tube pins have wedged the connectors open. The right sized tool is important; try a straight pin, sewing needle, small nail, etc. Stick to something metal.... a tooth pick will probably just break off in there.

This problem only seems to occur with 7 & 9 pin minatures...which is probably why they made those red & blue "pin straightener" devices.

Have fun, Greg
