I forgot to update this at the time, but ultimately, the supplier I found, in a very round about way, indicated that they weren't interested in helping me at the volumes I was interested in. I don't understand the round about nature of their response though. I would be happy if they would tell me right at the outset, "Look, if you don't want to order 10,000 of them then we're not interested." It would save time. It would also be nice if they would state right out what quantities they consider too small.

Ah well. I'm still not 100% certain that was the final result. They were so wishy washy, that I'm tempted to email them and try again.

However, I wonder if we might just try getting a few of these:

and rewind them with Litz wire.

Hmmm. Anyone have a definitely dead L2 coil? It might be useful to unwind it and carefully count the windings. I wonder if one can determine the number of strands in the Litz wire with a careful visual examination.
