mini-max tube amplifier
I built a hybrid tube/solid state amplifier today:
www.diyforums.org/MiniMAX/MiniMAXoverview.php
the colors are from some LEDs that are hidden under the tube sockets. part of the preparation is to cut apart the 2part ceramic sockets and bury a LED behind the hole ;)
sound quality of this amp is very good. no ICs used at all, just a tube stage for voltage gain and a BJT (bipolar junction 'regular old' transistor) stage for current gain.

construction time was about 8 hours. pc board and case were part of a group-buy; the rest of the parts are from mailorder standards such as 'mouser' and 'digikey'. the tubes were also purchased from the project organizer (tom).
