[ARC5] VHF Set Sensitivity

[David Stinson]

Just resurrected one of the scarce, perhaps even "rare" 
early R-13 VHF receivers- the one with black paint, 
a freq dial and a "twin-ax" connector.  
I've got a 1946 magazine photo showing this set 
installed next to an ARC-3.  
The front end uses 9003 and 9002 tubes.  
My TV-7 hasn't got a listing for these, so I 
haven't checked them.  Someone hacked this 28 volt 
version for 12 volts, then must have plugged it into 
a 24 volt rack because it blew the filaments on some
of the tubes, including two in the front end.  I had
some used ones, so replaced them, but I have no way of
testing the 9002 or 9003s.  I'm concerned because,
after alignment, the set's sensitivity for minimum comms
is about 3 microvolts.  For a "full quieting" signal,
it's more like 6 or 7 microvolts.  I'd like to test 
these tubes before going further.  Does anyone have 
a set-up for the TV-7 that will do 9002 and 9003?
Thanks, D.S.

p.s. With the exception of the electrolytics
( the 15 mFd audio cath. bypass was shorted 
  and the two 5 mFds where slightly leaky),
every bathtub cap in this set tested good,
and most of them are the WWII vintage type.
How'bout dat?

p.p.s. I have the 12-volt version, too, 
but it's in worse shape.
