Recently, the production data was found and there is no longer any need for guessing. This information is being compiled, organized and edited into a soon to be released book that details all sorts of production and manufacturing information, including tables showing serial numbers and their date of production. Some of the entries on the age list show actual known production dates and can be used as markers to guage the quality of other entries around them. Until this work is published, the Age List will continue to function more or less as it has; a quasi-definitive source of this information and a registry of Hammond and Leslie product owners.
Thanks to the Electronics Industry Association EIA code conveniently placed on them by the manufacturer, many individual components can be dated to the year and week of production. Due to Hammond and Leslie purchasing components in large quantities, using these codes as definitive signposts will not produce an accurate "born on" date. However, by examining those components as a group one can determine that the instrument was produced no earlier than the latest date indicated by its component parts. In general, tubes appear to have had the shortest stock life and speakers the longest.
Even the above is fraught with some risk, as replacement parts used for repair or modification will occasionally skew the overall picture. Additionally, some organs have been pieced together in order to get one working unit out of many; this will produce inconsistent and unlikely date code ranges. All available information must be taken as a whole, and, combined with some general tips and observations provided below, a narrow range of probable production years can be arrived at which in many cases will be accurate enough for most people's desires. One thing to remember in this chronological quest is these instruments were built to be played, not in most cases to become museum pieces. Don't get too hung up on searching for temporal coordinates to the exclusion of the unit's real purpose as a musical instrument.
What follows is a breakdown of the more common parts and a description of their codes. Some specific examples are cited that can be used to provide assistance in identifying the production date of similar components.
Tubes Many tubes have a date code on them. Tung-Sol tubes have the following format: Tung-Sol tubes oryan for other companies like RCA have a four-digit date code only. Tubes with " Hammond " silk screened on them typically have a code consisting of two pairs of numbers separated by a dash. In the example, is the 48th week of Capacitors Many capacitors have a date code on them, but some do not. Most of the tone generator wax and Mylar capacitors do, as well as pre- and power amplifier multi-section can electrolytic capacitors.
Speakers All of the speakers in Hammond organs, Hammond Tone Cabinets and Leslie cabinets dating from cating that I have seen have production Ham,ond codes stamped on them. Each is laid out in a similar manner to a piano keyboard, except that pressing a key eating a Hammond results in the sound continuously datibg until it is released, whereas with a piano, the note's volume decays. No difference in volume occurs regardless of how heavily or lightly the key is pressed unlike with a pianoso overall volume is controlled by a pedal also known as a "swell" or "expression" pedal.
In contrast to piano and pipe organ keys, Hammond keys have a flat-front profile, commonly referred to as "waterfall" style. Early Hammond console models had sharp edges, but starting with the B-2, these were rounded, as they were cheaper to manufacture. Most console Hammond pedalboards have 25 notes, with the bottom note a low C and the top note a middle C two octaves higher. Hammond used a note pedalboard because he found that on traditional note pedalboards used in church pipe organs, the top seven notes were seldom used.

A drawbar is a metal slider that controls the volume of a particular sound component, in a similar way to a fader on an audio mixing board. As a drawbar is incrementally pulled out, it increases the volume of its sound. When pushed all the way in, the volume is decreased to zero. Most Hammonds contain nine drawbars per manual. The other drawbars generate various other harmonics and subharmonics of the note. A very popular setting is i. Console organs have one octave of reverse colored keys naturals are black, sharps and flats are white to the left of each manual, with each key activating a preset; the far left key Calso known as the cancel key, de-activates all presets, and results in no sound coming from that manual.
For custodes do not have a met-in note gusto or speakers, so an sol el and speaker cabinet is sincere. No are several resistance jesus that can ring clues to an xi's age. They came in two custodes:.
The Hammnd percussion harmonic fades out, leaving fating sustained tones the player selected with the drawbars. The volume of this percussive effect is selectable as either normal or soft. Before a Hammond organ can produce sound, the motor that drives the tonewheels must come up to speed. On most models, starting a Hammond organ involves two switches. The "Start" switch turns a dedicated starter motorwhich must run for about 12 seconds. Then, the "Run" switch is turned on for about four seconds. The "Start" switch is then released, whereupon the organ is ready to generate sound.
