  Edd.B writes;

   The screen grids can be connected to the control grids with a
  resistor and the tubes are operated as a hi-u triode. Feed
  the screen grids from the feedback winding. Do NOT use a
  wirewound resistor for the grid to grid connection, use
  several 2 watt composition resistors in parallel.........
  
  While this idea will most likely work, it is kind of a
  poor use of a 100 Mz capable tube.
