The ZSP-1 (Stereo Preamp ver. 1) represents the first
in a soon to be entire range of simple kits built on
a flat plate. Attractive hardwood (or aluminum)
the chassis for a top quality look. The ZSP-1 comes
with all the parts shown above (except tubes), and a 12 page assembly
manual complete with schematics, assembly tips, layout
templates, and a high resolution layout photo.
circuit for this 5 tube stereo preamp was designed by
Steve Deckert in the Zen tradition with top grade parts.
It has a sound that is equal in quality to all of our well
respected Zen Triode Gear.
features a massively over-size power supply, tube rectifier,
and dual paralleled triode gain stages (one for each
channel) feeding paralleled cathode followers. Giving
it the advantage of a very low impedance but high voltage output.
This makes it able to drive almost anything including
long runs of cable. It
has one pair of inputs and one pair of outputs with
a simple ganged volume control by ALPS.
sound is clean and open, no noise or hum with excellent
dynamics and control. Just a hint of warmth makes
it ideal with both solid state and tube amplifiers alike.
can be rolled with 6922, 6DJ8 or 6N1P in any combination.
