Zen Triode mono SET amplifier kit
Up to 3 boards can share one
can be used to create:
A stereo amplifier (as shown above)
A pair of mono blocks
A multi-channel amplifier for home theater!
You supply the TUBES
The Kit comes as shown with proprietary
Decware power and output transformers. Audiophile quality parts are
used throughout, including ceramic tube sockets, 100K level control,
standoffs, binding posts and components by Vishay, Dale, Nichicon,
Sprague ATOM, Solen, and a high quality reversible board designed to
work on a flat piece of wood, or upside down in a steel or aluminum
(gain) control can be mounted on either side of the board, as can the
input jack. You can also remote mount either in the chassis and
run shielded cable to the circuit board.
This is a 2 watt mono amplifier configured as
a single ended triode and operating in class A. It uses a
single output tube, EL84 or SV83 and a single input tube, 6922 or
12AU7. The input tube is determined by installing jumpers on the
circuit board shown above.
It features a horizontal AC buss design that
allows you to connect up to 3 boards to one power transformer.

INCHES X 9.5 INCHES
1) A single power transformer and 1
board for a mono amplifier that could be used for a center channel.
2) A pair of power transformers and a
pair of boards for a pair of mono blocks.
3) A single power transformer and a
pair of boards for a stereo amplifier.
4) A single power transformer and
three boards for a 3 channel amp.
5) A pair of power transformers and
four boards for a serious 4 channel amp. Note: The AC buss of all 4
boards can ALSO be tied together putting both power transformers
in parallel for even more headroom / which btw, is the only way a 5
channel set up can be wired.
6) A pair of power transformers and
five boards for a 5 channel amp. Each board is 3 inches wide making it
possible to fit 5 of them inside a rack mount chassis as shown. The
power transformers can be mounted either in a separate chassis or in
the same chassis provided there is adequate depth.
7) A pair of power transformers and
six boards for a 6 channel amp.
We have successfully driven hundreds of
different loudspeakers ranging in efficiency from 90 to 100dB 1w/1m. On
90dB speakers it works nicely in smaller rooms or for late night out of
body experiences. 94 to 96 dB speakers are ideal in that they let you
play beyond a normal listening level and preserve the dynamic headroom.
When the basic Zen Triode Amplifier (that these are designed after) was
first released in 1997 there were a minimal number of "high efficiency"
speakers to choose from. Today that is no longer the case - they are
everywhere. We also offer several different types of loudspeakers that will work with this amp.
This amplifier requires no adjustments
or maintenance other than changing tubes every couple of years. It is a
self biasing design. The SV83 (6P15P-EV) or EL84 output tubes
wired in triode were chosen over 300B, 2A3, 45, and other triodes for
having the better neutrality and speed.

This amp is designed for premium quality
N.O.S. 6P15P-EV output tubes rated at 5000 hours. These Russian
military spec tubes are the top grade of what we came to know in this
country as the SV83. You can also use EL84's without adjustments of any
kind. You'll find the SV83's to be unparallel in speed and detail
- in part because it is a video tube with much wider bandwidth then a
normal audio tube. We think these are the best sounding most
transparent tubes available today. The EL84 (6BQ5) is a bit warmer
sounding giving the amp a different signature by just switching output
The input tube is a single 6N1P, 6922 or 6DJ8
- your choice. 6N1P's have the warmest tone, 6922's have the best
dynamics, 6DJ8's have the most air and micro-detail with a touch less
bass. You can also configure the board for 12AU7 and or a 12AT7.
