Looking for place to donate unique Philco Philco J-1930 Prototype
#3

Hi J Eibner,

Welcome to the Phorum.  Lots of Phriendly Pholks with Phine (See a pattern here?) advice.

It is very much a shame that these "home entertainment systems" have gone out of style.  It does look like a quality unit, and I hope you either find a home for it or keep it.

This is rather high end for Philco, RCA, Magnavox, etc. It is just a step below Fisher, Scott, etc.  Is this solid state or tubes?  The provenance, showing that this is one of 3 or 4 protypes is also very neat.

The use of a dual voice coil woofer was quite clever.  Motorola had a similar setup except that they used a higher powered PP 6BQ5 amp to power a "center channel" and 2 lower power single end 6BQ5 amps for the left and right.  I don't think that the center channel was an actual subwoofer with a cutoff at 300Hz like modern systems, I believe that they carried most of the left and right info as a "center channel" and, of course, most of the bass.  there were several schemes for "center channel" back in the early to mid 1960s.

The Satellite speakers are unique.  I have never seen them on American sets as a kid. I did see them on a neighbor's Grundig

The reverb is definitely cool.  Fisher had that option, as did Fender guitar amps, using a similar setup.  In my teen years, my neighbor had a custom console built, having one of the first solid state Fisher stereo receivers, a reverb, Garard changer, Ampex tape recorder and 2 12" Coax University speakers in Bass Reflex cabinets.

I have 4 units that have separately tunable AM and FM sections:
  • A Silvertone "700"AM and FM Stereo receiver, built into one compact speaker cabinet.  the other speaker for stereo is in another cabinet.  (consumer level)
  • A Scott Am and FM Stereo tuner. (Higher end).   Meant to be used with a Scott (or other brand) Stereo Amplifier.
  • A Pilot 602 receiver with separate AM and FM tuners
  • A Fisher 800C receiver.  This was rather top of the line, and received both AM and FM Stereo and FM Multiplex Stereo.  (t has an output and input to add a reverb and also had a line level center channel output.

Electrostatic speakers were definitely high end, and still are.
