T-421 Pictures

Mr. Steve Blair has kindly sent me the following pictures of his T-421 organ

Full frontal organ :o) - this is a really nicely kept organ considering it is at least 30 years old.

 

 

 

Closeup of the manuals. Tabs from right to left: Brilliance, volume soft, reverb tabs, vibrato style tabs, vibrato on/off (T-400 organs do not have selective/split vibrato), percussion reiterate on/off, percussion voices, upper manual presets, lower manual presets.

 

 

The 6-voice rhythm section in the lower right cheek-block of the organ. The white tabs select each voice's coupling to either lower manual or pedals on or off, the black buttons let you play the rhythm sounds with your fingers. ( Please note: I had previously stated here that the picture shows the Rhythm Rail - but I have since learned that this is incorrect. The actual Rhythm Rail device was found only in the T-300 organs and has 10 voices and an auto-accompanyment feature similar to what the Rhythm II and later Rhythm III devices have).

 

 

The organ with the back off. The major components are clearly visible:
  1. Vibrato line box
  2. Tonewheel generator
  3. Drum scanner (for vibrato)
  4. 12" speakers
  5. Leslie kit (for Leslie 147)
  6. Expression pedal housing
  7. Reverb tank
  8. Leslie unit
  9. Hammond Series 10 tone cabinet socket

 

 

The internal Leslie module exposed.

 

 

The two Leslie switches on the front rail control the external Leslie kit. The speed of the internal Leslie unit is controlled by one of the white rocker tabs in the lower left cheek-block.

T-582c Pictures

These two pictures were taken by yours truly in 2005. They are of a T-582c.

 

 

 

 

The last version of the T-series was by far the most elaborate. The control tabs and buttons were made coloured instead of being just white, the rhythm section on the 'top floor' was the Hammond Rhythm III device and a cassette deck was optional (this one has it, as denoted by the 'c' in the model name). The vibrato section allowed for selective or 'split' vibrato for the first time on T-series organs (except for in Europe - see the previous page) and the organ now had an actual Leslie output socket that was tied to the internal Leslie controls.

 

A selection of schematics for the T-series organs can be found on the Hammond Schematics page.

Download the T-500 owner's manual here (very large file!)

 

 

 


As it can be seen, the organ has moving dollies on it.

 

The keyboards and color-matic control tabs. The fat guy with the plaid shirt...well that would be me :o)
