Dennis;
Working from memory. The common connector that Charlie pictured is the one you'll find in ham junk boxes. The TBY
connector is almost the same except the "sex" is backwards. On the TBY the male pins are on the chassis and the female
pins are on the cord. I have had some luck swapping the internal parts to make it work with the TBY. You may have to drill
a new set screw hole in the cord connector, which is the one you want. Some filling maybe involved.
Again, working from memory.
