I helped my grandparents with vista for a while but after seeing how bad vista really is I suggested Ubuntu. They said no. A few days later when their computer would only boot to a black screen. Ubuntu was loaded the next day. I set everything up and now its so less stressful helping them out. As much as I don't like Ubuntu, its way better than having to deal with a computer that has vista on it. So far its working out.

what does this have to do with modern electronics? It's sure not going to do anyone good that isn't interested in analog. Plus the book you would want for tube amps is Radiotron Designers Handbook 4th edition. This book is the tube bible. My copy is from 1953.
I have 2 copies of the 3rd edition(1941). The interesting thing is that the 3rd edition has about 350 pages and the 4th edition has close to 1500 pages.
