Working on this TBX project and need a couple connectors, the two for the receiver (8 pin) and transmitter (4 pin). The male panel mount connectors are CUF – 49041 and CUF – 49043 and a PL-62 shell apparently will fit into the socket but not a PL-61
Because this is a original 1939 TBX Transmitter/Receiver reluctant to change out the connectors for anything else. Think I can modify a PL-61 that I have by drilling out a new hole in the body of the connector and be able to use that for the transmitter but the receiver is another story being that it uses seven of the eight pins for all the different battery voltages.
If anyone has anything or know what the appropriate connectors are called please let me know.

I assume the sockets on your TBX use banana plugs as mine does.  It is very easy to make your own connectors using the brass tubing from the hardware store.  I solder a wire to the brass tubing and cover it with heat shrink tubing. I have successfully cast the whole thing in epoxy, but it isn't necessary, and is messy.  Enjoy.

Best regards,

Pictures of the radio. The TBX family of radios pre dates the Second World War and was somewhat obsolete by the time of the war but that did not stop the USMC from using them in the Pacific. The early series just used one 837 in the transmitter with suppressor modulation for about three or four watts of AM and a 1C5 mixer and a bunch of 34 tubes for the IF, Detector, BFO and audio. Had a TBX 6 years ago and was gifted this original TBX just recently. They also produced a TBX-8 that was the same size but used newer tubes and components and had fancy features like PTT operation.

I took a look at my cables. The transmitter cable has porcelain inserts and the connectors are CUF 49040.  The receiver connector is CUF 49042.  There are probably Army version connectors that would fit too but can't help on those.

Didn't there used to be a fellow in Texas that sold WWII military connectors? I recall looking for an ART-13 connector but sold it before I got the project underway.
