I'm cleaning out a bit and I have a good quantity of these red, black, and green binding posts. Tektronix part numbers 129-1022-00 (BLK), 129-1023-00 (RED), 129-0064-03 (GREEN).
These are new unused old stock and are in their original bags as shown. Made by Superior Electric Co.
Selling in lots of 10 for $30.00 + shipping. You choose colors.
I have LOTS of black ones!
Cheers,
Corby
