Decware Zen Triode SE84CKC Integrated Amplifier *SOLD*
Good condition with box.
Manufactured from 2013 to 2015.
Updated to a more popular 1930's black textured finish. The best sounding version to date due to a re-voiced front end. Each amp also comes standard with cryo-treated beeswax caps. We named this update the CKC mod which stands for "Christmas Keeps Coming".
The Decware Zen Triode Amplifier is a single-ended-triode design using Russian 6P15P-EV or EL84 output tubes.
This amp features one output tube per channel, and both are driven by a 6N1P/6922 dual-triode input tube.
There are only one capacitor and two resistors in the signal path of this amplifier.
The internal parts are connected point-to-point, part-lead to part-lead with almost no wire and no circuit boards.
In addition to this extreme simplicity, there is also no negative-feedback giving you unlimited sound-stage depth.
This circuit features a floating output-stage that makes it possible to bridge the amp into mono without any loss of fidelity.
There is also a volume control with additional accommodations for two sources if you choose not to use a pre-amplifier.
The design also features a self-biased output-stage which is 100% stable making bias-runaway and premature tube failures obsolete. There are no tedious adjustments making this amplifier virtually maintenance free.
The amplifier ships with a 5U4 rectifier tube. In place of the 5U4, you can use a 5AR4, 5Y3GT, and certain types of 274B .
