Organ Guru :: Hammond A-100

Model A100 Series

(Manufactured from ~1959 through 1965)

Note:   Model A105 continued to be manufactured until January/February 1975.

 

Note:  Around serial number 20000, Hammond assigned a block of serial numbers to the decorator cabinets in the A-100 series (A-101/102/105/122/143 etc.).  This has caused owners to wrongly attribute the age of their instrument when based solely on the serial number, and consequently, many of the serial numbers reflected in the age list for this group are probably in error.  If your unit has a serial number in the 20000 to 30000 range you must check date codes to get an accurate reading of its production date.  Serial numbers after 30000 were reserved for A-100 models only.  When Hammond used up the decorator block of numbers they were reintegrated into the pool of general A-100 numbers.
