Yeah, mine had one of those 4 coil 120/240v regulator ballasts. I replaced it with a new 175w MH ballast since the old cap was shot and I wasn't able to find a replacement for a decent price. The ballast seemed to be on it's last legs anyway. I don't remember if mine was loud though, I only ran it for 5 minutes. I kept the OEM GE ballast though, didn't want to throw it out since it was the orignal ballast and still had signs of life. It's currently in the box the replacement ballast came in.
