Hi all,
I have a Leslie 45 that I have added slow motors to, and control motor speed (AC Fast, AC Slow, and DC stop) via external pedal. I want to add a 1/4" input for gigging with non-hammond keyboards. In stead of buying a leslie preamp, could I just use a pair of step-up transformers to boost the signal?

Is this the amp?
You could come in with a 1/4" right across the 10K level pot, disconnecting from the rest of the input plugs. You'd definitely need a preamp of some sort to realize full power from a guitar, but one would think a commercial keyboard these days would have enough signal umph to drive it. The headphone out certainly would have no problem driving the 10K.
While this schema helpfully notes the tolerance of the resistors, they left out a small note near the 10K level, which could have read something like "1.5V RMS for full output; do not exceed this level to prevent clipping" but they didnt care to provide that information.
