Default Dreaming of a power JFET complimentary pair.

So the other day I was thinking just how awesome an F5 amplifier would be if Semisouth ever decided to make a complimentary pair to their power JFET. I have read elsewhere that this is unlikely to happen because of the market they are targeting with their product. However, what if we could show them a viable market, that they may have not thought of, so they would have a reason to consider building and designing a complimentary pair. So what other uses, can you guys come up with for a complimentary pair of power JFETs, aside from audio? I am sure there must be other uses out there. If we could make a persuasive argument + show financial data to back it up, there is a chance they may listen.



I know it's a long shot but I think that this is something that we should try. I think that power JFET technology, now that it has been refined a bit, is poised to revolutionize the audio industry.

One area I could think of are lineair power supplies with source/sink capability. However, most of not everything high-powered is implemented by switchmode supplies. What other industry fields are there where lineair power may benefit from such devices? Other than audio, not much I could think of..

Try for some NOS Sony Vfets, 2SK82 and 2SK28.

Why not just build the circolotron?

Or the upcoming F6, which is not a circlotron but uses N channel devices.

So many amps, so little time. Must sleep less.
