Tektronix TM503 Mainframe with FG 504 Function Generator and DC 503 Counter:
$133.50

A Tektronix TM503 3-slot mainframe for test equipment. The TM503 enclosure currently has two modules installed in it: An FG 504 function generator and a DC 503 universal counter.
The FG 504 has been tested with an oscilloscope and shown to be in non-working condition. It powers up but only produces a signal intermittently. When it does work, it produces a distorted signal at a frequency somewhat lower than indicated, and sometimes jumps in frequency.The DC 503 works but has some mechanical damage: The front bezel of the unit has a crack on it and a missing piece, and the pull tab to remove it from the enclosure is missing. The reset button sometimes resets the display multiple times as it is being pushed in.
