Tektronix TM504 Mainframe with Plugins
This mainframe provides power to all four slots, has a working power switch, and only has a normal amount of cosmetic scuffs and dings for an instrument its age. Included is a set of matching plugins: DC503A frequency counter, SG503 signal generator, DM502A Digital Multimeter, and FG501 function generator. The DC503A and DM502A are in excellent condition and work perfectly to the best of my knowledge. The SG503 basically works, but the signal level seems to be out of calibration. It can still be used with an oscilloscope to set the proper signal level. The FG501 doesn't work. Maybe you can get it working, or you can at least get a good vernier from it. The price is essentially for the TM504, DC503, and DM502. The SG503 and FG501 are basically freebies for buying the whole package.
Tektronix 1240 Logic Analyzer
A fine 100 MHz logic analyzer from Beaverton, Oregon. I never got around to using it, as I had no room for it in my shack. It powers up and passes self-test just fine. Controls work well, including the touch screen. The second photo shows a close-up of the capture card configuration (two of the 9-channel/10 ns cards and one 18-channel/20 ns card). I also have three pods: two P6461 pods and one P6460 (with on probes on this pod). Also has the nice cover for it.
