1960-1970 capacitors still working?!

Good question. STC listed applications as Power measurement, AGC/voltage regulation, remote controlled resistors etc.

I have a couple of 10k B14s that I was thinking of using for a thermal RMS converter (a lot bigger thermal response that heater/thermocouple and heater/diode) but haven't got around to it yet. They'd probably work well as RF power sensors too. Theoretically you could use them in place of the old R53 self-heating vacuum thermistor for Wein bridge oscillators, but the bead is a lot bigger and there is more thermal coupling to the outside world through the multiple lead connections.


P.S. I see that you can still pick them up on ebay occasionally, eg: https://www.ebay.co.uk/itm/124302590120

A lot of vintage IC's in ceramic and also a bag full of large electrolytic capacitors.

I measures a few of them and they seem fine?

Are they usable, is testing them with my Peak LCR45 and ERS meter enough to determine that?
If so, I want to sell them on Ebay but I don't want to sell bad stuff of course...

Thanks!
