OVERVIEW:
This is the 10th year anniversary edition of
our original Zen Triode amplifier. It is 2 watts x 2 or
6 watts x 1 single-ended triode design capable of driving loads
down to an almost ridiculous one ohm.
A completely purist design, hand crafted
amplifier with only 1 capacitor and 2 resistors in the signal path.
Even hook-up wire is eliminated with everything connected
parts lead to parts lead. Of course there is no circuit boards
and no Chinese parts. Our amplifiers have proprietary US made
power and output transformers of outrageous quality. It is an
amplifier that will get the undivided attention of even the
sickest audiophiles!
The only problem with this amp is the price.
Audiophiles who are always looking for a better sounding
amplifier have owned and presently have amplifiers costing many
times this amount... so it becomes almost impossible to wrap
their brain around the simple fact that this amplifier could sound
better than theirs. If you're a serious audiophile, try it on our
30 day money back trial and see for yourself.
STYLES:
This amplifier comes in two basic styles
made possible by interchangeable hardwood bases. The amp shown above is
in the black base. The amp shown here is in a contemporary solid
walnut base. You may choose between the two bases
when you order your amp. We can also custom manufacture the base
below in any hardwood, including exotics for an extra cost.
FEATURES:
The SE84ZS amplifier has both direct
and variable inputs so that you can use it with or without a preamp.
We recommend if you own a preamp to try both using and not using
it to see which is actually better.
IDEAL SPEAKERS:
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 almost
ideal in that they let you play beyond a normal listening level and
preserving the dynamic headroom. When these amplifiers were 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. If you own speakers that you love and are afraid
this may not drive them understand two things: A) It will drive them
louder then you're expecting and B) you can bridge these amps into mono
blocks. Because of the power increase into lower ohms, you will
net 6dB of additional power. Same thing as doubling your power...
twice.
SPECIFICATIONS:
This amplifier requires no adjustments
or maintenance other than changing tubes every couple years. It
is a self biasing design and self balancing meaning even unmatched
tubes become matched when installed. The SV83 (6P15P-EV) or EL84
output tubes
wired in triode were chosen over 300B, 2A3, 45, and other triodes for
having the best sound and imaging.

VOLTAGES
This amplifier comes standard with our World
Voltage Compatible Transformer. Your amp will be automatically wired
for the correct voltage for your country and be supplied with the
correct removable power cord.
2ND GENERATION:
The original version of this amplifier was
called the SE84CS, the S stood for "Select". It was a select
version of our original amplifier, the SE84C, that we still make
today.
DESIGN NOTES:
The original
SE84CS
Design notes still apply.

TUBES:
This amp is shipped with graded 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 tubes.
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. Again, a powerful tool for voicing your amplifier to your
particular tastes.
The rectifier is a 5U4G and can be substituted
with a 5AR4 or compatible rectifier. Many owners of this amp like
using the 274B. Each rectifier change will also make audible
differences in the sound and performance of the amplifier.
CABLES:
This amplifier is so transparent that
differences between cables will now become big differences.
If you don't have good interconnects or speaker cables or just
not sure how good yours are we offer affordable reference quality
cables that will let you hear how good this amplifier and your gear
really is.
