  • Sale
  • Regular price $1,499.00


This is a very special limited availability product.  We are offering this because we have a few thick silver SL face plates left over after switching to the fully remote Fet Valve CFR model.

A brand new unit available for quick delivery right now.

The Fet Valve CF SL audio stage is all tube, using 12AT7 tubes for gain and 12AU7 tubes as cathode followers. This combination, done with outstanding multiple regulated power supplies, provides the amazing dynamic range, transparency, and load drive capacity that we demand. It will interface seamlessly into and improve the most demanding audio systems.This engineering has resulted in the lowest noise tube preamplifier we have ever offered.

The Fet Valve CF SL is an astonishingly natural, engaging, dynamic, high-resolution preamplifier that can interface seamlessly into and improve the most demanding audio systems.

Only the highest quality parts are used. We use 1% precision metal film resistors and all capacitors in the signal path are select polypropylene types.

The Fet Valve CF SL also includes an exquisite headphone amplifier capable of driving the most demanding headphone loads.

Power Supply and Layout
AVA has long been an advocate of rock solid power supplies, and the power supply used in the Fet Valve CF SL is no exception. The high voltage supplies are based around six active high voltage regulators, one for each tube section. This power supply design takes supply noise and interaction down to nearly zero. In addition, there are separate regulated power supplies for the tube heaters and the headphone amplifier. Smoothing capacitors are carefully selected modern, high-reliability, high-capacity units.
The main circuit board uses multiple isolated ground planes strategically interconnected to eliminate the effects of ground currents. A very quiet custom made shielded power transformer is used.

The Fet Valve CF power supplies are incredibly quiet and rock stable platforms on which our audio circuits can perform their best.

SL Chassis Design.

The SL Chassis has a precision remote volume control, precision balance control, six sets of line level inputs (with one input being used for the optional phono section, if specified), tape in and tape out jacks, and two sets of line audio outputs.

It has push button controls for tape monitoring, stereo/mono, low gain, and filter functions.

The premium silver face plate is finished with our incredibly durable double-anodized process. All input and output jacks are gold plated, and a removable IEC power cord is provided.

Dimensions: 17" wide x 12" deep x 3.5" high. Shipping weight is 17 pounds.
