  Instead of 829B (a WWII vhf twin tetrode) do you mean 572B (a '60's
  vintage overgrown 811A triode with 2 or 3 times the plate diss & higher
  rated plate volts)??

  Are you sure Glen?  An SB 200 uses a pair of 829B tubes.  I've been told
  you can't put a pair of 811 tubes in there because the power supply is
  too much for 811s.   On the other hand, a Collins 30L1 uses four 811
  tubes and many hams have put in two 829B tubes in place of the four 811s
  and they report the 30L1 purrs like a kitten, hardly knowing the 829B
  tubes are there.. and they last practically forever.
