GE model SP-20B satellite speaker
12/5/2004 7:09:43 PMMike White
I just acquired 3 clean examples, originally for parts. These are satellite speakers that receive an RF signal thru the AC mains from some master receiver or phonograph (switchable from one of two channels). I do not have the master unit or its model number. I took the back off of one unit, and found date codes on the tubes and IC that indicate it was probably made in 1965. Based on the tube complement and supply voltage, it would put out about 2W into its 7.5" speaker. The unit could be either floor-standing or wall mounted (wall mounting kit and instructions are included in a small compartment in the back). The wood cabinetry is impressive; the wave soldering of the PC board is NOT! I have been unable to find any information online about these units, or GE's remote speaker system. Before I tear into them, I was curious if anyone can shed some light on these curious items: perhaps the model number of the master unit, schematics, etc. Are they somehow worth preserving?

Mike, SAMS Set 671 Folder 11 covers this "Home Music Distribution System." Looks like Robert has a more complete syatem.
