There may have been other differences between the two. T-12A and T-12B were effectively the same organ with speakers being the only significant distinction -- "A" had console speakers and "B" had external "gyro" cabinet only.     > As fas as moving it...get losts of helpers...they are quite heavy, as > alll the generators and amps and other circuitry is self-contained. > Also, check to see that the pedal board is on dis-connect plugs or the > pedals will be teathered to the console, which will make moving it > more of a challenge! > Rick in VA   The pedalboard will be attached via a set of connecting plugs and, Rick's right -- the suckers are heavy.   From a technical/musical perspective, these instruments were built around a single rank of analogue sine-wave generators which were combined at different pitches to create rough approximations of various stops. As a result everything is heavily borrowed and duplexed.
