Steve Force Posted March 10, 2012 Share Posted March 10, 2012 I searched but didn't find any other posts on this so..... I fired up my Hammond XK-3c and Leslie 122 this morning and found I could no longer control the Leslie speed from the Hammond. I checked all connectors,all settings, even pulled the flash card to go back to default settings, but no joy. The problem happens even if I do not hit the fast speed button (or kick it with the expression pedal) the Leslie starts spinning fast and stays there. Even if I disengage the fast speed button, or change presets even, the Leslie remains spinning fast. I powered down all units several times, waiting a couple of minutes before re-powering, but the problem happened again. Started slow, then automatically kicked into high. Anybody else had this problem? If so, what did you do? Steve Force, Durham, North Carolina -------- My Professional Websites Link to comment Share on other sites More sharing options...

Steve Force Posted March 10, 2012 Author Share Posted March 10, 2012 Hmm.. Relay. That sounds possible. Steve Force, Durham, North Carolina -------- My Professional Websites Link to comment Share on other sites More sharing options...
Joe Muscara Posted March 10, 2012 Share Posted March 10, 2012 If it were me, I'd try to set up to test the Leslie itself if that's possible. That's what I did with mine (45) when I got it. That said, the 45/47 is a six pin and the wiring is pretty straightforward. I have no idea how the 122 is wired. "I'm so crazy, I don't know this is impossible!

MoodyBluesKeys Posted March 10, 2012 Share Posted March 10, 2012 Leslie 122 uses a DC high voltage relay for speed switching (whereas the 147 uses a 120v AC relay(. Original idea was to take a B+ feed voltage from the Hammond preamp, and ground it to operate the relay. If for any reason (relay coil gone bad, wiring problem, or the XK3c is no longer providing the DC voltage to operate - the relay would stay open, and the speed would remain high. As I recall, the B+ voltage was usually taken with a plug in adapter that connected to the 6x4 rectifier tube socket, so it would have been over 300 volts.

Jim Alfredson Posted March 10, 2012 Share Posted March 10, 2012 It's most likely the 1122 conversion kit. Steve bought the Leslie and 1122 kit from me and I had that same problem once before. It turned out to be a resistor in the 1122. I really doubt it's the relay in the 122 but I suppose it could be. Keep it greazy!

bhodaway10 Posted March 10, 2012 Share Posted March 10, 2012 I had a bad relay in my 122 and basically it would get stuck on fast. I had it replaced by eis - Bob Schleicher. Btw, I got the eis relay which is now made by trek (but Bob's design.) Fwiw, I have the 1122 kit too and he told me it was the relay not the 1122.
