A friend of mine, using First Watt schematics, built one of their SIT amps and it is a very good solid state amp. That amp, and others I've heard from First Watt, are so much better than most other solid state amps if you have the right kind of speakers (I do, and my friend runs 105 db/w speakers).
Take good care of that amp because I don't think that replacement transistors will be easy to come by now and in the future.
