Hi, Paul. I have a nice collection of vintage public address amplifiers, some of which date back to the late 1940's and, of course, use vacuuum tubes (or "valves" to you guys...a neat term [Linked Image]). Lots of fun if you don't mind working around B+ on the order of 800 volts or so!! They actually work, and I use some of them on my jobs.

Rabbit: If I ever learn how to use a digital camera, I'll send you a pic. of an old 400a. 3 phase disco still in use at my community theatre building here in Wharton. This thing is almost the size of a refrigerator and must have taken five or six STRONG men just to grunt it into the building and mount it on the wall. As it is, the mounting bolts extend all the way through the wall to the outside of the building and through a couple of pieces of strut. Would love to have this behemoth in my collection, but my wife would divorce me if I brought this thing home! [Linked Image]
