Are you thinking about building a pair of 4xc250b's.  I have a sub assembly 
that would be a perfect start.  This was the modulator sub assembly from an 
mackay maritime 500 khz A1/A2 (modulated cw) rig.  The assy consists of a 
pair of sockets (these are the sockets with the build in screen bypass) a 
blower, the bias supply, and the fil supply.  2  very new 4cx250B's with 
plate caps and ceramic rings.  
There are HV switching relays and other parts. this unit was recertified 
about 4 months before I removed it and the tubes  were removed from the 
spares inventory just before the FCC inspection.  The unit actually was run 
on mcw twice while in service, both for FCC tests.
