Well, In response to your first question, after 2 years I'm FINALLY in the process of putting together my 2A3/300B SE amp science project. I did all the machining and woodworking on it and it's been sitting boxed up. Hopefully by Christmas, (can I say that here?), it'll be completed. Being more mechanically then electronically oriented, it's being more of a challenge then I expected. Luckily I have some freinds that are way better @ this then I am to help out. In response to your 2nd question, I've only listened to Solens and Hovlands in my PP amp and prefer the Hovlands by a long shot. I undestand there are way better out there for a lot more money. OK, time for a snooze.
