I have a Hickok 580-A Tube Tester that I've been having a hell of a time trying to get calibrated correctly. Someday I'll figure it out (it doesn't help they used factory tubes for a lot of the calibration)
I love my Tektronix 2430A. I have some of the Tek 160 modules for the modular oscilloscope from the 50s, although I haven't really tried that. If you saw the guts, it's a point-to-point wiring masterpiece.
