Texas Instruments Silent 703/707 print head anyone?

Hi, last weekend I cleaned and restored a TI Silent 703 printing terminal. A rather common type with its whopping 300 baud transfer rate - nevertheless a piece of history. It was easy to fix a broken trace on the keyboard PCB (corrosion) and to roughen the idler roller for better grip on the paper. Now there is one issue left: The print head is missing one dot (infinite resistance: burnt out) and one dot prints weak (resistor seems to have twice the resistance of the others, which are all around 95 Ohms). As these terminals were produced in large numbers and the printhead/ribbon cable combo was a user serviceable part someone might have some spare parts... So: if you have a new or used part #2310472-0001 printhead, thermal I would be interested. It is a 10 wire ribbon cable with the print head. It was used in the 703 and 707 and probably also in other devices of the TI 700 Silent family. Martin
