> For the matched toshiba I think that EUVL may be selling ...
No I am not. I have none in stock.
Especially for the F5X, you need well matched Toshiba NNNN-PPPP's and IMHO only Zhou Fang has a large enough batch to offer those well matched.
He has thousands of each type. I don't know of anyone else who has.
As to the original Fairchilds, you could check out the old GB threads and see who bought how many (hundreds) then.
And then you could see who is the nicest guy nearby among them and if he might be willing to let go of his treasured stock at a reasonable price.
Yes, I still have some. But I am the well-known bad guy here, and I'll undoubtedly rip you off !!!
So please do not contact me for Fairchilds unless you are extremely desperate.
And, on top of that, I use Toshiba myself for the F5 balanced.
And yes, I have built (the balanced F5x) using both, as already published years ago.

No, I didn't try all 3 in the same circuit. Honestly I thought you already did that, but probably you went directly balanced.
I have some experience with the IRFPs and the Toshibas, I also had the Fairchilds at hand, but so far never came around to try laterals. At the moment I'm toying with bipolars.

just for fun, looking at a IRF TO-262 (surface mount)
but havent found a matching N part

how about mating your 28N15 with this FQA22P10 instead ?

or FQA33N10 might be a match

FQA17P10 http://media.digikey.com/pdf/Data Sheets/Fairchild PDFs/FQA17P10.pdf
FQA16N25 http://media.digikey.com/pdf/Data Sheets/Fairchild PDFs/FQA16N25C.pdf
Tested the F5 build with Toshibas with my fostex fe206 based BLH speakers.
Sounded pretty good with icreased bass compared to the IRF variant. Considering the price of 3x for Toshibas compared to irfs, the effort may not be worth. Moving on the next one.
Cheers.
I've, been there done that
and very much satisfied! Extremely work-friendly enclosures and very robust.Don't hesitate in taking even the 5U!
