Hi,

Those with very long memories may recall that back in the late '60s or early '70s, Radio Shack actually sold an accessory box with a pair of analog meters that you inserted between the speaker outputs of the stereo receiver or amp and the speakers. Fun to watch, but not lighted.

Loved your comment on using a thermometer for those new Onkyos!
