Very nice presentation. Reminds me of my old slide rule days. Old school but they were very accurate as well. And you had to use your brain to read them. Also good! Thanks for sharing, Tim.

I still have mine too. I used it back in the early 80's during my electrical/instrumentation training. To be honest it took me a while to change to digital. These are still being built today so that should speak to their worth. I was interested to find that the telephone techs used the Triplett 310. Good video.

audio background is crap, fix it.
