If you have a 7-10 watt 240 ohm resistor you can remove the 35W4, connect the resistor across pins 3 & 4, connect a 1N4007 to pins 5 & 7 (cathode to 7) and remove the pilot lamp. I would also bring it up slowly on a variac. I haven't done this before but I know I'm headed for the same boat you're in and this is my plan when it happens. Anyone else?
