My warmnest thanks to those who sent me information on the Create RC5-3 rotator controller especially those who emailed the instruction manual and the contact infomration for Create in Japan. As suggested the problem was in the PNP/NPN transistors in the servo circuit and once those were replaced the unit worked properly. As a matter of interest the differential servo circuit works off of a +12v and a - 12 v rail which is supplied by a power supply that uses the indicator lamps as the bleeder resistors. One of mine was burned out and I could not find the miniature screw-type 12 volt, 0.1 amp lamps in the parts list so I replaced themn with wheat seed lamps and shunt resistors to match the bleed current.
Create in Japan was very responsive to my requests and provided detailed information - more than needed as it turned out. Still the customer service of Create deserves commendation.
