OPERATION MANUAL MODEL : ZMA - ZEN MYSTERY AMP
REV 1 MAR 2014
ABOUT
The Zen Mystery Amp is a class A push-pull tube amplifier featuring an ultra linear
output stage with zero negative feedback. It is built it a high mass solid steel plate
that has been machined and designed to damp out resonances.
There are no circuit boards in favor of the far more difficult but better sounding
point to point topology where everything is symmetrically laid out in three
dimensions and hand soldered with both channels in a mirror image ensuring every
part and wire length is matched between the two channels. The layout is
structured to have the least number of solder nodes. The result of these efforts is
world reference imaging and focus that we feel is not obtainable any other way.
Shown above is a Zen Mystery Amp ready for it’s final soldering phase. What you
see completed in the picture is only the power supply. It is now ready for the hand
full of parts that make up the audio circuit.
