[Amps] 4CX250F Tubes

[Bill Smith]

Just came in to possession of a box full of new
4CX250F tubes.  Thought they may be a very low cost
alternative to the 3-400Z tubes in my Swan Mark 1 amp.
 I know it would take quite a bit of work to do but I
would be in tubes for the rest of my life!!

Can these tubes handle the 2500vdc the Swan puts out? 
I know they are rated at around 200vdc plate voltage.
73,
Bill
