[Johnson] Looking for resources and possibly some help . . .

[Richard Knoppow]

    Good to see you here. There is an archive of past posts at:
http://mailman.qth.net/pipermail/johnson/
     This list does not seem to have an archive of files or 
pictures but you may find some help by searching the mail archive 
by thread or subject.
     I found a bunch of stuff via a Google search, an example is
https://faculty.frostburg.edu/phys/latta/ee/ranger/restoration/restoration.html

Might be helpful. Also don't forget to search YouTube, the google 
search showed some videos there.
    As with most equipment the first thing to check is the power 
supply.
    You need a VOM and its helpful to have a good scope (IMO the 
single most powerful trouble shooting tool). A general coverage 
receiver is helpful.
    Mostly patience.
