Tektronix TM-503 – Power Module Mainframe 3-Slot Chassis

I had purchased this at a local hamfest last year. Apart from testing it, did not put in any use in it. It will probably find a fuller use w/ another owner. So, decided to sell it (I have a matching Digital Multi-meter module DM-501 for sale too). Asking $105 OBO. Priced to Sell
