[AMRadio] A special day today

Remember the Collins 32V-1.  Exposed plate caps on the 807s' and 4D-32; but Art Collins (his engineers) used an interlocking device when you lifted up the lid.

A relatively simple, inexpensive microswitch killed the high voltage.  

Collins Radio forever.

    What I still wonder even today is how WRL/Leo Meyerson could make such death 
    traps and get away with it.

  It's my understanding that Leo's designs, tho a bit eclectic, started out OK. It was his Bean Counters that
  messed 'em up.

    I still have a Galaxy V that when you life up the lid, there is the PA cage 
    fully exposed.

  I had a Galaxy V Mk. 2 for a couple of years. Not a bad rig, really...

    What was he thinking?  Could it have been $$$$$ by shaving costs.  No 
    interlocks on the "big boy: - the Globe King 500.

  TELL me about it!!!   The cost cutting done on that rig is a crying shame...  it could have been one of the
  GREAT ones. The most grievous cost cutting measure was in the PA and modulator plate supplies, IMHO.
  They seem to e to be just barely adequate, with PA plate voltage too low; with another 300 - 500 VDC there
  the PA plate efficiency would be a whole lot better.

  One thing...  Leo's rigs used some FUNNY tubes!

  I have a Globe King 400 that's gonna be restored...   I had one HELL of a time finding a pair of V-70D finals!

  And the Hytron 5514 modulator tubes (in both rigs)  aren't that common either...   tho you can modify for
