For some reason, this post disappeared a few minutes ago, so I will re-post:
Hello froggers! I am excited to try something new! For the last few years I have been looking for a suitable socket for subminiature vacuum tubes and I may have found a "current production" possibility. There is a MillMax version of socket for 8 pin transistors that are PC mount. The Mouser link is: http://www.mouser.com/ds/2/273/136-259791.pdf
. The manufacturer part number according the Mouser is: 917-43-208-41-005000. The specific socket that is closest to the Frog Tube Preamp PCB submini holes is the .230 one. If you look at the pictures attached here, the socket pins are straight. In the picture where I am holding the sockets, you will see that I had to "form" or bend the pins slightly to get it to fit the submini solderable pin holes on the PCB. Once they have GENTLY been bent, they fit right in and can be soldered. I have not soldered one in yet, but I will be populating a board with this configuration and let you know how it goes. You will see by the data sheet PDF I referenced above, there are little contact clips inside each pin hole so it will make good contact. If you are going to try this, DO NOT clip off the pins once soldered and remember to solder the socket on the non-component side. Meanwhile I will be experimenting with this. The contacts are rated at 3 amps, so there should be no problem with the .6 amp heater wires. By the way, if you do put this in, point the little "bump" to pin 1 on the Frog Tube Preamp PCB for better reference and use my guide in the documentation to determine the pin numbers on the Russian submini tube. The marking for pin 1 is on the component side. Sorry about that. In future versions of the board, it will be on both sides. The good thing about this, if it works, is that you won't have to solder a submini tube permanently into the board! Another thing I am going to try, because the sockets only cost about 3 dollars each, is to solder a tube directly to a second socket, so it will be even easier to plug into the socket on the board. I hope that is able to be understood. As I do this, I will take pictures and add them to the thread!
