  There were several variations of tube 1 kW transmitters: the Gates
  triode boxes, the RCA/Collins/Bauer/McMartian/CCA/Wilkinson/etc tetrode
  boxes, and stuff that didn't fit into these two categories like the linear
  amplifiers (RCA and Gates Vanguard), and very old systems like Western
  Electric (Doherty), older RCA stuff, and whatever I missed.

  ONLY THE LAST TWO RCAS USED 4-400s: BTA-1R AND BTA-1T. COLLINS MADE A HUGE
  XMTR THAT USED 833s, AND GE MADE ONE, TOO.  THE ODDBALL TUBES IN THE WE
  DOHERTY WERE ELECTRICALLY NEARLY THE SAME AS 833s.

  design that they used was gutless.

THIS WAS  TRUE STARTING WITH THE BC-1J. THE BC-1F THAT PRECEEDED IY WAS
HEAVY DUTY.
