I finally got around to replace the dead TO-3 power transistors in my
VR-14. They are mounted on the power supply regulator heat sink using TO-3
sockets made by AUGAT. Unfortunately one of the sockets has been broken by
somebody in the past by over-tightening the transistor mounting screws.
This may have been the root cause of the power supply failure as one
transistor was doing all the work with the second transistor's collector
lead having poor or no connection. There are two NPN transistors in
parallel to double the power which is not a very good design anyway.
I am trying to find the original Augat sockets.
Here are some links to photos showing a closeup of the socket and the
threaded insert with the originally crimped collector tab which broke out
of the bakelite socket:

I would be grateful for any help trying to source these AUGAT made TO-3
sockets. I had no luck finding stock of these with Google and Ebay.
Thanks and best regards
