Marshall Classic 5 Power Control

A new front panel knob gives continuous control of the power output to give you nice Marshall crunch at all volumes.  This utilises a unique approach that is not wasteful of energy.  Bringing green technology to your amp.

 

This mod requires the installation of our own custom circuit board.  A further advantage of this design is improved filtering of the pre-amp power supply.  The Classic 5 is a single ended class A power stage with cathode bias but power control board also is suitable for installation in high power amps with fixed bias supplies as it can automatically adjust the bias as the output power is varied.

Best of all this board can be used in almost any tube amp up to 200W.
