This is a class A, all tube amplifier that is based off of a 6SN7 preamp tube and a 6V6 power tube. It was a fun project, but it's not very practical. The sound is no where near as good as my solid state chipamp, which was half the price as the tube amp. The tubes look really cool though. There is something about retro obsolete electronics that is interesting.
This amplifier was built from a schematic found at http://boozhoundlabs.com/ before the website blew up, I'll post a link to the schematic when they come back up.
