[ARC5] RC-54-A, RC-55-A Test sets....

[Craig]

Hi Mike: Thanks for the additional info. The manual that I have a copy 
of is the one revised in July of '56.  The reason for wanting better 
photos, was to read the specs off the voltmeters. I've found that the 
loading specification changes from version to version. I was able to 
determine that the voltmeters on the panels were 1000 ohms per volt, 
while the couple that I have found so far were 666 ohms per volt. 
Dealing with the voltages in these radios, I would be concerned that the 
lower spec meters would have a propensity to load the circuits enough to 
cause problems.  I've got one meter on the desk now and two more enroute 
and in the hunt for the others.
