I’m new here so if this is not the area I need to be please feel free to point me in the right direction. I have had my Collins 392 receiver for about 13 years. My uncle gave it to me when I was a kid and he has since passed... along with his knowledge. I have the field manual and the technicians repair/ maintenance manual (both original). I've made about 3 moves with the receiver and during this last one something happened to it. :S. The issue I am having with it is that the Megacycle control does not turn all the gears that it needs to. The position Indicator on the back does not move when I turn the MC knob. I dug in a little farther and found that the gear that is attached to the position indicator shaft was loose. So I tightened it up and lubricated everything to spec and it is still not engaging like it is supposed to. I can take a flathead and adjust the MC by turning the position indicator on the back and tune in AM radio stations (so my radio is functioning, just not the mechanical aspect of it.). I have searched all over the net and called tons of places throughout Texas trying to find someone who has once worked on these guys. I’m finding out that there are few still around. I work for the National Guard and have taken it over to the guys in the comms shop but that was like showing them a walking talking dinosaur, they had no clue how to even begin working on it. If ANYONE has any knowledge about it or knows where I can buy parts for the mechanical end please HELP a fella out. I also have a few PRC-77's if anyone is interested. Thank yall for your time and have a great day.
