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 replacement sockets:
The following closeup shows 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 with Google and Ebay.
If all else fails I will try to repair the socket, but I would prefer a new one.
