I would so much see an elegant solution using only dual monolithic N jfets.

Triodethom - Yes, they will. Most likely by the end of the year.

This is not conjecture, and I am not at liberty to say any more about it. (Yet)

I dont think we can blame Linear, on one hand they may already be stucked stabilizing process yield for P channels and on the other hand they need good financial report for their investors. We could probably show support if we combine our interest by filing up interest sheets with real demand quantities.

Just my 2 cents.

I'm thinking the same thing but my goal was to build the F5 to hear what all the fuss is about. If I designed something before actually hearing the F5 I doubt I'd produce something that sounded even remotely like it. Papa has lots of experience and intuition about the sound of his amps so I'm hoping he'll have time to whip something up for us soon.

Now that there is a pent up demand for the J74 type part they may be able to overcome whatever difficulties there are/were in making this part - since they've had the LSK170 for years now, there can be little doubt that they would most likely have wanted to provide a compliment sooner than later. I'm thinking that they are thinking they can put more $$ into getting the process to work now that there is a greater demand and no other source(s) for this part.

Shame that Toshiba decided to junk the line...

PS. ottopilot, the F5 is two things: a simple easy amp to build and 2) a chameleon - it changes character with bias, parts and implementation.

Maybe something else that will work but, I don't know that there is anything as good as the Toshiba parts. Most manufacturers like Pass and Ayre etc. bought a lifetime supply of them.
