Most of the regulars here will know this but for the sake of some of our younger readers...

The first time I ever saw an Altec amp was in the factory I worked at. Three of them powered the PA system. I was always very concerned because no one ever turned them off. EVER.

Those amps ran for over 25 YEARS continuously and were never serviced even once. I believe they were the 1590 Model.

The equipment made by Altec then was literally so dependable they were actually UL listed as a fire signaling device. Think about that.

Are there any amps built to that standard today?
