No need to add resistors. The extra voltage is a good thing, as the VT71 chassis is "voltage starved" IMO. The 37ohm resistor I'm pretty sure is just there to protect the selenium from inrush current. With diodes, this is not an issue so one could decrease the value of this and get more voltage, and better performance such as better sync lock (I'm using 20ohm).
As for the capacitor ballast, at 60Hz at less than 1A they are hardly being stressed at all
