Preamplifier Ypsilon Electronics PST 100 MK II Silver
Description
The Ypsilon PST-100 Mk2 is a flagship tube preamplifier engineered around custom-wound, 31-tap transformer attenuators rather than conventional resistor networks to achieve ultimate signal purity and micro-detail retention. Its active gain stage utilizes a single-ended, zero-feedback Siemens C3m pentode (triode-connected) coupled via a custom output transformer, providing 16 dB of gain with a maximum output impedance of 150 ohms. The external-grade power supply employs 6CA4 tube rectification and choke filtering, while all internal connections are point-to-point hand-wired using proprietary pure silver wire. The transformer attenuator is positioned after the valve stage to preserve dynamic expression, and a passive version (PST-100 TA) is available for systems requiring no active gain.

Ypsilon Electronics
Ypsilon Electronics was established in 1995. It was founded by two sound engineers with extensive experience in the field of live music reproduction. It was not only their experience with live music and concerts that provided the necessary knowledge, but also their technical background in electronics; it was precisely this that helped shape their vision of how a high-end audio device should function and what level of reliability it should demonstrate. It was precisely their love of natural live music and their determination that compelled them to transform this passion into technology – technology that combines traditional approaches with modern, pioneering design solutions and processes. The result of these efforts is a range of unique products that convey the true essence of music to listeners… emotion!
