Item Description

This Tektronix TM504 Power Mainframe with DM502A, PS503A, DC503 is in very good used condition. It does show some signs of use and there are a couple of imperfections with the modules but overall, everything works as it should.

The DM502A works but the range select buttons can occasionally be a little glitchy, probably needs some contact lube / cleaner. The PS503A works fine but the right hand current limiting pot doesn't turn (it's all the way up now). The DC503 works but there is one segment out on the second from right digit (see second to last picture).

The last two pictures show: the DM502A reading the PS503A output voltage and the DC503 reading a 500KHz signal from a signal generator and the DM502A measuring a 91KOhm 2% resistor.

Please ask if you have any questions.
