Title: Plug type Trivia Post by: ke7trp on October 24, 2012, 12:55:03 PM What is the name of the connector? Used on Tbolt for BIAS and used on GK500 for PTT cable.
Old Tbolt has 4 pin and the one I fixed up has a 5.. I need a 5 otherwise, I have to spend 2 hours replacing the connector, Its burried.

The probable reason yours has a 5 pin is because they were used on many late 50's and early 60's CB transceivers as mike connectors and so previous owner probably cannibalized the chassis connector from a transceiver and the plug from a mike cable.
I believe the part # for the 5 pin plug is Amphenol 91MPM5L so probably the 4 pin is Amphenol 91MPM4L. It might be less aggravating to just go to Radio Shack and pick up one each of these. The hole diameter should be fairly close.

What we ended up doing is to rip the correct 4 pin socket out of the old parts tbolt and put it into the new one. Glad we did. The guy wired up the bias wrong with the bypass caps. Problem solved. C |
