>You did it wrong. ?The GDT do not replace the resistors on the grids. ?You

tube socket. ?You directly ground the grid. >?Then one GDT goes from  each
filament wire to ground. ?That?s the way it?s done.

Then also wire a 100K @ 3 watt  MOF directly in parallel  with each  GDT.
2 x GDT's required.  2 x 100 k resistors required.   GDT's are  160 V
rated.  Same as ameritron uses.
