Thank you for your comments, Al. But in an amplifier's vacuum tubes (as
Jim, myself, and others discussed earlier in this thread), are charges
moving from anode to cathode opposite the flow of electrons?

observed and felt, but you can't point to a gravity object.

Actual electrons drift about the conducting medium at rate of something
like 1 meter per hour. On the other hand the charge is propagated at near
the speed of light. Negative charges flow one way; positive the other.
