• Shunt-style balance control
• heavy-duty seamless aluminum chassis
• Precision components used throughout
• Low-noise "star" grounding topology
The UV-1 (UltraViolet) preamplifier is based on a circuit that Atma-Sphere has used for many years, but not marketed before. About 40 years ago, Ralph Karsten began developing his own circuit for use for friends on a budget but with high end audio aspirations. It was originally used as a modification to the venerable Dynaco PAS-3. Over a period of decades, the circuit has seen a lot of refinement. It is a simple circuit based on a very capable and refined 6SN7-based line section with a simple phono section based on 12AT7s.
The preamp is available in four forms: a basic line stage, a headphone power amp that also works as a line stage, a full function preamp with high output MM capability, or with the addition of a set of Jensen stepup transformers works with any low output moving coil cartridge as well.
The headphone version of the UV-1 uses the full tube complement of the UV-1. It has four inputs and can be used as a line stage as well. This version does not have a phono section.
