Of course John, thank you for pointing that out.  Also note that i think 
the coil Terry has runs a voltage doubler (level shifter) on the plate 
supply??
If so, a red plate seems to suggest a very strong chance of something going 
wrong.  Even pushing my 811A's to 2kvac seemed to cause arcs some times 
though the coupling was low and could have caused the arcing.
