I had the same ballasts and had a ton of problems with them trying to run different bulbs. I ended up ordering just the ballast(electronic) from J & L. Then I opened up the cases and replaced them all.
I found that the coil and core ballasts PFO were using were bulb specific and now with the new electronic ballasts I can run them all.
