This is an 8 watt Mono Integrated Tube Amplifier Kit  that is easy to build, sounds great, and is just fun!  This Mono Integrated Tube Amplifier utilizes 5670 triode and 6005 pentode tubes.  The amplifier has built-in volume control so that it can be driven directly from a CD player, tuner, etc.  The amplifier operates on 120 or 240 Volts, 50 or 60 hertz and may be plugged into a convenient outlet.

The 8LM Mono Integrated Tube Amplifier comes in kit form (K-8LM) .  The kit comes complete with all the resistors, capacitors, tubes, connectors, circuit board, transformers, and necessary hardware for mounting on the provided "bread board". (For the 240 customer they must supply the proper power cord for their area.)

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
fire or shock.
