[BC] tube sound (tube transmitters)

[Paul Smith W4KNX]

What you should have done was rewire the Collins box with neon bulbs behind
the tubes to make it look like the tubes were lit and have the various
meters show that they were working and the pilot lites working and disable
the rest of it.  That way you could have had your cake and eat it too.
Visitors would have enjoyed the looks of old tx, while the real signal was
eminating from the equipment rack.

Mark,
  Seems like I only got 6 to 7 months out of the 4-400's I used with the
Collins 20V-3. I had to rotate the tubes every 4 months for the thing to
sound loud enough to compete with a 5 KW neighbor that was using a
Harris MW-5. I also changed out the 807 in the driver section as well,
when I changed out the 4-400's. The Collins "DID NOT" have the audio
quality that my Harris or Armstrong has! I did good just to get 120%
positive modulation out of the Collins, and that's with a new set of
tubes.
