I put the C-70 back together except for the top and bottom covers. I also left the power lamp out. I am going to replace it with something else. I put the partially reassembled C-70 on my test bench to start going through the service manual checks. I would have done that regardless but especially now because I changed out all of the trimmers. When I changed the trimmers I tried to set the new ones as close as possible to what the old ones were set at.
