SSP-3A solid state pre-amp is designed to replace the original tube pre-amps in standard Hammond
In addition to basic pre-amp replacement, all units feature built in percussion circuitry, reverberation, auto power on
circuitry for 11 pin Leslie
22H, 22R, 31H above serial #5200, 122, 122A, 122R, 122RV, 122V, 142, 222, 222RV, and 242). Although not used in
normal installations, all units also have provisions for using a floor type (remote) swell control. The SSP-3A may also be
ordered with optional features including Auxiliary amplifiers, Effects loop, Remote tone and percussion controls. These
items, as well as hook up details for many other Leslie models are covered after the normal installation instructions.
Because of both electrical and mechanical variations in different vintage Hammond organs, the SSP-3A is available in a
number of different versions. The SSP-3A-1 version is specifically designed to replace the AO-28 pre-amp used in B-3, C-3,
D-152, and RT-3 model organs ONLY.
