[quote author="tk@halmi"]Hi Brad,
Thank You for the offer, much appreiciated. I have a good number of decent matches so I wil be fine. The Linear parts seem to be on par with the Toshibas otherwise. It may be just their test/qc is not as good as Toshiba's.
Cheers,

Or maybe they don't make as many of them (highly likely at this point). It is after all a very simple sorting process, involving a quick measurement, unlike something that is measuring a picoamp and so forth.
I'm tickled that we have an alternate source, and a sustaining source for the dual SK389. I hope LIS prospers.
When I conversed with LIS via email the man said their dual parts should actually be quieter than the Tosh because of the interdigitated construction. I didn't press him on the whys and wherefores of this assertion, or in what frequency range the alleged superiority would manifest, but I would be fascinated to know, if anyone has gotten some data. I've been too damn busy, and as well am sitting on about a thousand 2SK389V's that I bought when Borbely confirmed Toshiba had stopped making the part. Most of those will probably go to the crematorium with me, but they confer a sense of security in the meantime.
