I knew that multimeter looked familiar. And I haven’t seen nor used the thing in 30+ years. But I knew exactly where it was,so I decided to pull it out of its long storage. Not exactly what you have there, but it is close enough. I have the Weston 4440, which is just a smaller version of yours. I never used the thing and it was given to me by a friend who worked for UL labs. The old “C” cells still in it, and to my surprise not a single one of them leaked. I’m going to toss some new batteries into it tomorrow and see if it still works.

Tantalum capacitors are electrolytic capacitors. They just use tantalum for the plates instead of aluminum that are used in aluminum electrolytic capacitors.

srtamplification, yes, good clarification. I was using the popular shorthand of just assuming everyone knows that "electrolytic" by default means "aluminum electrolytic" and "tantalum" means "tantalum electrolytic". Given the wide range of viewers, I should perhaps have explained that.

​@@youtuubaI'm not sure many people know that. I've heard several people say the same thing you did, " they're polarized capacitors, but they're not electrolytics." I have made way worse mistakes in some of my videos. That's why I stopped making videos. I'm just not good at it. I refuse to sit down and script things like some do. I like the spontaneity, but most viewers seem to like a more polished product.
