My grandpa has this nice old boat anchor in his basement. A prototype

capacitor--he says it drifts badly without it.

I assume this is a capacitor with a particular TC that is used to
compensate for the drift of some other parts with temperature?

If so, you need to know both the value and the TC, and then you can
order what you want out of the AVX catalogue.
