Hello, Brian-</P>


It's good to hear you're interested in the F-100 and you're rightthat they're not very common, although they do show up on eBay occasionally. While I haven't actually heard or played the F-100 Extravoice,I'd imagine it sounds very much like my S-100. Both use very similar tube-driven tone generator circuits designed originally by Hammond engineer John Hannert, I believe originally for the Hammond Solovox during the 1940's. The idea was expanded and became the S-series of Hammond Chord Organs in the early 1950's. The F-100 Extravoice falls somewhere between a chord organ and a spinet. One of Hannert's last patent ideas, it is, as Hammond said, "somewhat different." The RCA jack you asked about is an input, intended for a phongraph. It would probably work well with some type of rhythm box playing through the internal speakers using this jack. Instruments above serial number 8556 do have an external tone cabinet socket though, according to my information. If you check eBay, you may sometimes see books of popular music of the time arranged just for the Extravoice.</P>


"The Extravoice by Hammond is a new and somewhat different instrument as comopared to Hammond Organs produced heretofore. The single 52 note keyboard controls the output of three independent tone generation systems. The 12 bass pedals are served by an additional tone generator.</P>


The 'Extravoice' division is played by the keyboad, and is used for playing a melody with th right hand. This division plays only one note at a time. If several keys are layed at once, only the highest note will sound. The 'Treble' division is independent of the Extravoice division but is played by the same keys. Its notes augment those of the Extravoice division and also make it possible to play full chords. The 'Accompaniment' division is independent of the treble and other divisions, and, as the name implies, provides a means of playing accompaniment chords and counter melodies. The 'Pedal' division has 12 pedals (C to B) which provide bass notes. Only one pedal note can be called upon at a time because of the sustaining circuit employed.</P>


There is a group on Yahoo called hammond_zone that you might be interested in checking out.</P>
