Hello, Nick. The 122 supplies a dc voltage which the leslie kit
(through those half-moon switches) fires back down the audio line.
All you need do is put a switch into that line and you can control
the speed of the 122 with it. I have mounted foot switches on both X-
66 expression pedals here and can control the speed either with my
foot or with the choral/tremelo switch. BTW, if you ever find your
122 won't change speed (assuming your switches have been repaired and
are known working), this can happen because of a bad voltage
regulator in the leslie. That is the one tube that glows (is it an
OC-3? I don't have the prints in front of me). Unfortunately, I
left my digital camera over at a friend's house, but can retrieve it
if you need schematics of the leslie kit. The 122 schematics are on
the side of the amplifier chassis. Pull the amp out and the
schematic is pasted on the side of the chassis. If you need a print
of the adapter kit for the old B3s, A-100s, etc, e-mail me at
j.r.hampton@... and I will take some digital photos in
black and white (and fool with the contrast to try and make it as
readable as possible) and e-mail them to you.
Best of luck and have a gooder!

G'day from Australia everybody . I arked up my gear today ( C3 /
122 ) and the Leslie won't slow down. It has fast only. My half moon
switches are obliterated by a doorway, but hopefully there is another
way to get slow speed for now until i can get new switches or fit a
push-down button which i would prefer anyway. Any ideas PLEASE? I
like fast Leslie , but not all the time. I play like Jon Lord so need
the slow very badly.By the way I played around with the control on
the expression pedal control today. I thought i had growl before,
but this is insane - and i got the info thru' the zone. Thanks
everybody. This distortion is amazing. I've had the C3 for 30 years
and was not aware of that little screw in the volume setup.
