You can just as well use matched pairs of 2SK170's to get much better matching then Toshiba ever did with the dual units. There are even special heatsinks to join them as a single unit for better thermal stability. You can also use a MAT02 with some small changes to the circuit as was documented in the KGSS article on Headwize.

I know that it exists - there was a group buy on DIYaudio some time ago.

The MAT02 is, AFAIK, not available anywhere. I'll take a look for the 2SK170s, though.

EDIT:

I found these on eBay. I figure I can clamp them together with some Arctic Silver to get proper thermal matching. Should I go for them?

Gentlemen, The LSK389 are available like the post said. Just call Linear Systems. I built my P2P KGSS 6 months ago and they work great. The guy at Linear Systems (can't remember his name) is great to deal with and very helpful. If I remember right, a pair of LSK's with shipping is under $20 bucks. A little expensive for some, but the KGSS is worth it and sounds great with my ESP950's. My total cost including xfrm and PC boards from Mouser was around $400, not including any casing. If anyone is interested in building one P2P, PM me and I can give some great tips on building one including power supply tips, parts etc.
