[ARC5] OS-8 scope, transistorizing

[WA5CAB at cs.com]

There are at least four different NAVSHIPS manuals on at least five 
different OS-8 models.  Plus several Signal Corps manuals.  OS-8E/U, at least as 
originally built, has the same tube lineup as OS-8C/U, of which it is a minor 
modification.  Over the years, I've heard several rumours of a solid state 
model, but I've never actually seen one.
