My recent obsession with the tube TV restoration hobby started with test equipment fix-ups. The C-3 is a good beginning since it is so simple. I cleaned it up, used De-Oxit on the switches and replaced the caps. Some of the half watt resistors around the voltage select switch were off, I replaced them with one watts. I also added a pot across the 470K resistor so I could adjust the sensitivity.
After the C-3, I fixed up a B&K 465 CRT tester and a Leader LAG-27 Audio Generator, no tubes in those. Now I'm working on a B&K 747 Tube Tester that I got a good deal on (I think). I also have a EICO 368 TV-FM Sweep Generator waiting.
