This Tube Amplifier Kit is easy to build, sound great, and is just fun!  The Tube Amplifier utilizes a 10GV8 triode-pentode tube; which provides 8 tube stereo performance with just 4 tubes.  The amplifier has built in volume control so that it can be driven directly from a CD player, tuner, etc.  The amplifier operates from 120 Volts 60 hertz and may be plugged into a convenient outlet.

The kit comes complete with resistors, capacitors, tubes, connectors, circuit board, transformers, and all necessary hardware to mount on the provided "bread board".
A finished case is available for the 12G Stereo Amplifier.
