  I would use about a 1k ohm at 10 watts to start.  It looks like you need to drop 95volts across #54 what use to be the field coil.

The main things to watch for are the voltage at what looks like #38A the 4 uf cap 190v and how hot the resistor gets. 
 
You will be able to tell how close the 1K is once it is up and running. You might even start with a 1.5k ohm.
!!!!!!!!!!!!!!!!!!!RESISTANCE IS FUTILE!!!!!!!!!!!!!!!!!!!!!!
