those flakes in your 866s are mecury.  if they haven't been run in a  while 
you should let them sit with just the filaments on for a while, to make  sure 
the stuff gets where it needs to be. They look nice, but the mercury  vapor 
rectifiers need to be treated well especially after a long idle  period.   You 
can direct sub a 3B28 argon rectifier tube, and not  have to worry about the 
866s. They don't glow as much, but are more tolerant  tubes.
