On a side note: I have a footswitch connected to the volume pedal. I just noticed that when I kick the switch for fast, it works fine until I lower the volume of the organ, When the volume is lowered, the fast speed disengages. When I raise the volume the fast speed reengages. I want to start with the cord, but I'm thinking it maybe something in the amp. Your thoughts!!! Is that strange?
I would look at the switching voltage at the Leslie amp. The DC voltage is mixed with the signal. If the DC switching voltage is marginal, the signal can cause it to go above and/or below the switching threshold. Your description of the problem sounds a little backwards to me but I would start there anyway.
Well I should also suggest checking the power supply voltages. I thought this was a rebuild and assumed that was not an issue. Low voltages can cause this. It could be a bad relay but I've never heard of one causing this symptom.
I don't have one, but I hope to purchase one at some point for my Leslie model 51 speaker. One thing I like about it is that I have the option of keeping "stop", which I rather like right now for playing, say, Doors material. The thing I especially like is that George is willing to talk about the PWM he does, that gives me confidence that this unit is unlikely to damage my motors.
I'm also a "KISS" guy and want a reliable speaker. It seems that converting my 51 with extra motors is likely to be less reliable. I also really like the sound of the 51 as it stands, would hate to lose it via a woodworking accident.
The only thing against this unit is that it's computerized, but since it's a computer I can't fix, I would make an exception for it and allow it in my musical gear sphere. (Computing professional here...music is supposed to be play, not work)
