    I own a couple of vacuum tube emission testers, a Knight 600 Series and a Heathkit TC-2. I noticed that the TC-2 has an extra tube socket, a mini 5-pin. The Knight does not. However I have never encountered mini 5-pin tubes in the North American radios I have seen. I’m curious to know whether anyone has encountered such tubes, and if so in what type of equipment and which era. Thank you for your comments!

    Would love to see a photo of the socket in question. I don’t own a TC-2 to check it out. Thanks.

    Sure, I just took a close-up picture of my TC-2 and the little 5-pin is the socket in the center of the attached photo. Thanks.

    The TC-2 manual states it’s a 6 pin tube socket but I have no idea what type of tube would use it. Maybe John at Pacific TV would know.

    You’re right: the socket’s "center hole" appears to actually be a metal pin connector. That makes it a 6-pin miniature socket 😳
