Keyed signals are separated by pitch register and by clavier the registers having sustain are keyed electronically (in the LS' case, these include the pedalboard 16' and upper-manual 8' and 4'), while the non-sustain registers are directly keyed.
Various tricks are used to compensate for an abnormally minimal set of generators, including foldback, frequency division, and-most ingeniously-frequency "doubling". Tone generation is done using a frequency-divider system, producing asymmetric pulsewaves from the master oscillators, and squarewaves from the dividers. Along with the "Lincolnwood" SS and SST models of the same year, it was the first Lowrey to incorporate sustain, made possible by clever use of neon bulbs and unconventional vacuum tubes. Introduced in 1957, the LS was the first model in Lowrey's "Holiday" line of relatively small and inexpensive spinet organs. As we already have pipe organs, transistor organs, and digital organs as distinct and not-necessarily-interchangeable categories, so should be tube organs! I hope it encourages further renewed interest not only in Lowrey's tube organs, but the entire class of instruments generally. At this point, this article may as well be called "A Treatise on the Lowrey Vacuum-Tube Organ." Whether or not it is worthy of that title, I believe it is the most comprehensive piece on the internet about such things to date. Lastly, there is a video demonstrating the sounds. Then comes a long discussion of its electronics, explaining the function of most circuits, some important yet now-obscure ideas that Lowrey based their designs upon, and the merits and demerits of several tube-based designs. Following the history lesson, I recount the amusing story of how I acquired my Lowrey LS, and detail the various repairs performed on it. This article has become much longer and more detailed than originally intended it has expanded to cover not only the instrument shown above, but also the overall history of the Lowrey Organ Company and products thereof, with emphasis on their tube-based organs made between the mid-'50s and mid-'60s.

LOWREY ORGAN SERIAL NUMBERS SOFTWARE
I've edited it so that each year appears on a single line below (because I don't want CW S&T software tripping me up), and then put them in chronological order: I took another look at those serial numbers, and realized that it was probably a case of the webmaster not formatting/reformatting the information properly. You might want to contact that business (Pump Organ Restorations) for clarification on the serial numbers: As low as I could find was 501 West 14th Place. The modern West 14th Place seems to survive in fragments, and I couldn't find that specific number range (85-89). In 1889 they were located on 85-89 West 14th Place, Chicago, IL. This is just about all the information that’s survived the passing of time on the Hamilton Organ Company. I found some information about the Hamilton Organ Company of Chicago,, U.S.A., along with some serial number ranges, but the way they've formatted the serial number information is confusing: That's so nice that your family had fun with this instrument.
