Many years ago I was given an Allen-Bradley brand Bradley Amplifier, the "Perfect Audio Amplifier". This is a three tube, resistance coupled amplifier. Mine has 2A3 type tubes. It looks like it was intended to work as the amplifier stage for a radio as there is a "Detector Plate" label at one of the binding posts.
The chassis is Bakelite and the connections are silver plated binding posts. The Allen-Bradley logo, along with the binding post labeling is molded into the chassis. All in all, a nice looking vintage amplifier.
I used to work at Allen-Bradley (now Rockwell Automation) in Milwaukee. They have a nice museum about the early days of the company tucked away in the factory. That museum is the only place that I have seen anything on the amp. They had a reproduction of an ad for the amplifier and other radio parts from the early 20's hanging on a wall at the museum.
I have been looking for a schematic and any other information that is available for this amplifier. I haven't found anything. If anyone has some information on this vintage amplifier please let me know.
