Tube Testers and Classic Electronic Test Gear provides an overview of pre-1970 (the vacuum tube era) radio test equipment. It begins with an extensive discussion of tube testing and use of testers, and progresses into curve tracing. The different types of testers are compared; emission, dynamic and mutual conductance, and testers from 23 different manufacturers are tabulated and pictured.
The book also covers VOMs, VTVMs, Q Meters, Grid Dip Meters, Capacitance and Inductance Bridges, Signal Generators, Signal Tracers and Oscilloscopes. It includes brief company histories of the manufacturers. Useful for radio collectors, vacuum tube enthusiastes and historians. Over 300 photos and illustrations.

anyone have a decade box?

I know a couple of places where you can get kits, but (shudder) analog gives me the willies.

Analog is kinda easy, but then so is digital, a decade bos is just abox of resistance that you hook up to something and adjust until you get the results in the ballpark of what you need so you can put in a resistor or a variable resistor in the spot. Analot, especially tube technology was difficult for me, I like to understand why and how, but sometime you just have to know what is expected and what they symptoms are when it doesn't do what it is supposed to do. I have a TV that had the vertical go out, I opened it up and there was a cheap variable resistor that fell apart. I can junk the damn thing or use a decade box to find out what the resistance was, the cheap thing crumbles when I tried to tighten it, and I didn't use much pressure on the damn thing. My Dad had gazillians of good ones that don't fall apart when you look at them.
