The idea to build a tube amp arose at a party, where all good ideas start. It stayed just an idea for about two years, due to other important things. This winter (2008/2009) the amp got my attention again. So I bought some books, googled for examples, searched explanations and gathered other info. Arnova and I then developed the first drafts for the amp. Later we visited some electronics fairs to get tubes and sockets. I have to be honest, eventually I bought new transformers and tubes. At the fairs I couldn’t find any proper power or output transformers, suitable chokes and half of my EL84 were bad. Reconsider buying old(er) parts.
