Charlie,
I had a ballast fail on me last night. I replaced it with two
51 ohm resistors in parallel inserted into #2 and #7 socket positions,
Use 2 watt or better. A bit of shrink tubing on the leads will keep
them away from the socket shield mount. If you don't have carbon you
can get MOV s in 3 and 5 watt values from Mouser. It works well for
me.
