Here is a Stereo Integrated Tube Amplifier Kit that is easy to build, sounds great, and is just fun!  The Stereo 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 can operates on 120 or 240 Volts and 50 or 60 hertz and may be plugged into a convenient outlet.

The 16LS Stereo Integrated Tube Amplifier can be purchased in both kit form (K-16LS) or fully assembled (16LS).  If you desire to build the kit, 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.)

Model 16LS Stereo Integrated Tube Amplifier

Model  16LS
    Page Updated October 2018

   Input Impedance = 100k ohms
   Input connector =  RCA jacks     
   Output Impedance = 4 ohms each Channel
   Output Power = Push Pull 16 Watts per Channel  (in to 4 ohms)
   Speaker Impedance = 4 to 8 ohms
   The circuit is a Class A amplifier
   Minimum Input for full output = .5 V
   Frequency Response = 20 to 20,000 Hz
   Total Harmonic Distortion at 1 Watt <1%

CautionThese 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.
