[Amps] Eimac 8560A Tubes

[k7fm]

"I have four (4) Eimac 8560A tubes new old stock in the original boxs that 
need a home. Don't have a clue as to value other than what some tube guys 
lists say. Anyone interested? I believe these are similar to the 4CX250 but 
are conduction cooled."

These might be useful for someone who has the conduction cooled SB-230 amp. 
They could not be run grounded grid, but could be run as a conventional grid 
driven amp with a resistive load on the grid and normal screen voltage.  You 
would need a screen voltage supply and regulator.  Not simple, but one way 
to save the amp when the 8875 tube well runs dry.
