Hey! Great discussions. Thanks for the thoughtful inputs.

Guess and go by weight is the only clue I'd have on these unmarked ones.

Right on. Nothing to lose, really. Maybe something gained.

Just a guess, but if the impedance is mis-matched, you could blow out the
output stage of the unit. I'd be careful.
