the q-4339b is the correct part. it isnt an inductor, it is a flyback transformer (alright, almost an inductor). you want the T6. but you are not going to get it from coilcraft. no free samples, part cost is $10 each, and shipping/handling is another $10. they got tired of people raping them of free samples on the transformers and the choke inductors. there are about a dozen posts that will tell you this!! check out renco for the transformer, or talk to mastero, he might be able to sell you one, hopefully cheaper than coilcraft.
definately do a search for sproggy inductors or transformers... much info is awaiting you!!!
