Having recently struggled a little
with re-stringing the dial cord on a vintage
Realistic (Radio Shack) Patrolman−50 Radio, it really became apparent
why the Sams Photofact Folders were of
such value to electronics servicemen. Unlike the tangled mess of dial cord shown
in the ad, I had the advantage of being able to carefully open the chassis and photograph
the routing and wrapping of the broken dial cord around pulleys and shafts. Even
so, a lack of experience required some trial and error to get the tensioning correct.
No doubt many unqualified radio owners attempted to fix their own broken dial cords
prior to breaking down and committing to spending a few bucks to have a pro do it
correctly. The tight quarters in my portable radio had me using tweezers to do some
of the routing, unlike the dial cord path for my
1941 Crosley 03CB console style radio which was easily accessed
once the chassis was removed from the cabinet. I would have gladly paid for a Sams
Photofact Folder for my Crosley 03CB if one was available, but alas one was not.
