[Milsurplus] R-174 Puzzlement

[Richard Brunner]

re:
" I dunno -- this has never happened before, so maybe somebody can 'splain
it
 to me. ...  Recently got an R-174, AN/GRR-5 --   Never come across this.
Might be a couple or three bad,
 some weak, but not nada.  Tell me -- how can it be zero for 8?  ...  Or
maybe (paranoia now) this rx was
 used to park some pretty, but dead glassware?  "

Parking dead tubes is not unheard of; somebody thinks he's pretty clever.  I
have also seen "any" tube stuffed in just to fill the set and sell it.
