An enameled wirewound Walt...not a ceramic type.

Absolutely not!  It is there as a current limiter only and must be able
to survive the hit long enough for it to pass or a fuse/breaker blows.

 
  Any recommendations

You need 10-20 Ohms or so depending on the tubes and the amount of
current limiting. A typical value may be 20 Ohms @ 25W. In a HV line over
3000V or so putting 2 or more resistors in series to spread the HV
breakdown path is advised. 

I sell 6.3 Ohm 15W Dale's at $2.50 if ur interested in a series string of
2 or 3. Other sources are any of the standard catalog houses that carry
Ohmite, Clarostat, Dale and similar quality brands. 

BTW, congrats on winning your RFI lawsuit !
