I recently picked up a GE ballast that included a printed copy of GEH 4251 (Mine is labelled GEH-4251B). When I have time I'll scan it and upload a copy on LG.
It's a instruction and datasheet for GE's fluorescent ballast with some parts explaining various ballast characteristics, similar to what Advance has on some of their older catalogues.
Thank You for this! I have been looking for this for years! I wonder why this was so hard to find?
This seems to be the 'only' source of this document now I bet the B suffix is just a revision or something?
PS: Sorry for not getting back to you sooner I was not feeling that great but I am Okay and on the mend now!
