Here are pix of some of my vintage test equipment.
This Readrite 432-A Tube Tester was introduced around 1940. It works well, and I like using it on my older tubes just because it’s super cool. I made some custom mods to it (note the pot and test points in the right hand storage compartment) that make it a breeze to recalibrate at any time.
It’s an RCA WO-33A Oscilloscope. Didn’t work when I got it. One of the first successful restorations I did. New caps, new line cord, some wiring repairs inside, and some calibration steps, and it works very well now.- General Radio 1310A Oscillator
