Re: Need help with ertl rc tractor from the late 70s-early 80s
It sounds like the 4640 running on 27 or 49mHz.....those boards go bad, everything in there is analog. There arnt any contacts in the tractor and prolly not any in the radio either. Its all pots and diodes. Unless one is an electrical engineer........
