[Amps] Russian Capacitor

[Mike]

Hello,

What is the value of a capacitor with the following markings (I 
believe it is a Russian make): KB?-10xb2200n? note: the "?" are for 
Cyrillic characters?  Is the value 2200 pF at 10 KV?  Plan is to use 
the capacitor for blocking the DC and passing the RF between the tube 
and the Pi-L output circuit in a GS-35B amp.  Please let me know if 
the capacitor will or will not handle the voltage and/or current at 
1500 W output, ~3000 V DC level.

         73,
