Reply to "TMCC Cab1 red knob spins freely - won't hold its speed setting"

Thanks Ricko.  I haven't had a rheo blow, but can imagine how much of a surprise that would be.  I recall now also some inexplainable differences between Cab-1's knob resistances when that was what we were predominantly using (pre Cab-2) and that was prior to much use on many of them.  I'll open mine up and see what I can do.
