I'm looking at the Hybrid Tube/MOSFET amp by Erno Borbely. There's an article here:

I'd like to do a low-buck point to point version.
It looks like all the transistors and MOSFETs are tough to get. I've found them on specalty sites for around $10 ea, but I'm thinking there's got to be an equivalent in the Mouser catalog for a buck or something.
Here's the list of suspects:
Q2 - 2SA872 (Hitachi (now Renesas) - Silicon PNP - complimentary pair with Q5 - 2SC1775)
Q3 - 2SJ79 (Hitachi - Silicon P-Channel MOSFET - complimetary pair with Q4 - 2SK216) or 2SJ313 (Toshiba - complimentary pair with Q4 - 2SK2013)
Q4 - 2SK216 or 2SK2013
Q5 - 2SC1775
I've spent a couple of hours with Google and haven't found any clues for equivalents. I spent a while looking at the datasheets, but I don't have the skillz yet to figure out how to pick an equivalent.
EDIT: http://www.bdent.com/ has the parts for sane prices!
