I was just re-reading this thread too and was wondering the same thing. If you need any 2sk30 transistors, let me know, I could donate a few to you if needed. I did the Ampslab 20 for $20, and have a handful left over. I shotgunned my SX-3900 and all is well and it runs clean and cool.
Good luck BTW, looks like you have a good working knowledge of things. (better than I did when starting mine).
