$82.49

Vintage Hickok 51X dynamic mutual conductance tube tester with set-up data chart, working fine but probably needs a calibration, and in good-VG physical shape. 4 tube circuit, and the 83 rectifier tube is new nos. Line adjustment working fine, and shown testing known good 6L6 tube. This tester is for the earlier type radio tubes. Cabinet in good solid shape, is missing a few feet, and the top plate cap lead is missing (easily replaced). Selling as-is for some minor attention.
