About This Listing

Allen Gyrophonic Speaker system. Pre dates Leslie speakers. 1940s - 1950s. Super rare. Stereo tube power amp.  Rotator spins but would need a switch to control speeds.  Tested with a variac (see video) to confirm as functional.  Power amp works as well but would need a pre-amp to boost a line level.  Looks clean inside. 2 x 15” Alnico speakers and 2 x 12” alnicos that spin. I think both 15” speakers have been patched but sound good.  Been on my “restore list” for some time so passing along a project but at least it is functional. Would be a cool addition to any studio/collection. Measures 64”x40”x24” - humongous!  I have it listed as “local pickup” but will assist buyer if interested in setting up shipping/logistics.
