Here is a Mono Integrated Tube Amplifier Kit that is easy to build, sounds great, and is just fun! The Mono Integrated Tube Amplifier utilizes 10GV8 triode-pentode tubes; these provide 4 tube stereo performance with just 2 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 K-11GMono Integrated Tube Amplifier comes complete with all the resistors, capacitors, tubes, connectors, circuit board, transformers, and necessary hardware for mounting on the provided "bread board".
Model 11G Mono Integrated Tube Amplifier
The 11G Mono Integrated Tube Amplifier is designed to operate from the audio output of CD players, tuners, etc. and uses an RCA jack for the input. The amplifier is designed to operate from 120 Volts 60 Hertz and may be plugged into a convenient outlet. The Mono Integrated Tube Amplifier is designed to operate with a 4 to 8 ohm speaker.

Caution: These Amplifiers may be operated as
supplied, however voltages in excess of 240 volts
are present on the board and the tubes get
very hot. It is advised that the amplifier be mounted in a
well-ventilated metal enclosure to reduce the potential of
