Stromberg Carlson theater amplifiers

posted by Frogman on October 5, 2006 at 7:28 am

As a old theater sound buff I recently found an old Stromberg Carlson AP 54 amplfier that apparently came out of an old theater in Toronto Ontario.

It mounts on a 19 inch rack and used a pair of 866A mercury vapor rectifiers and 811A output tubes.

Does anyone have any knowledge of this amplifier and or know where a second one can be found?

I’ve never heard of Stromberg-Carlson making a theater amplifier. This must be rare.

As part of the electronics division of General Dynamics Corp, Stromberg Carlson manufactured a line of PA amplifiers as well as home hi-fi amps, tuners and console radios (all monophonic as I recall). I believe that General Dynamics-Stromberg Carlson division withdrew from making home and commercial audio gear by the time stereo rolled around. I know that they had a line of rack mounted amps, as well as school paging/intercom systems so it doesn’t surprise me that they built equipment for theatre use.

I’m actually looking myself for one to convert to a bass guitar amplifier. If you find more than one, please let me know where one is. If you can’t find a second, and if you decide you have no need for the one you’ve got, let me know if you want to sell it. I’ll let you know if I find a line on any. Thanks,
