Excellent Fet Valve CF SL vacum tube preamplifier

  • Sale
  • Regular price $1,395.00

This 2017 production Fet Valve CF SL is in excellent condition.  We received this preamplifier as a trade up.

The preamp’s black faceplate has a front panel selector switch, precision stepped volume control and balance control. There are pushbuttons for Input/Tape, Low Gain, Filter, and Stereo/Mono functions.

There are six sets of line level inputs, tape in and tape out jacks, and two sets of audio outputs. There is a standard stereo headphone output driven by a low output impedance current amplifier circuit that follows the main tube line sections.

The Fet Valve CF SL is our unique cathode follower design using two 12AT7 and two 12AU7 tubes, one of each per channel. Each plate of each tube has a  separate independent regulated power supply, unique to AVA design and eliminating the subtile fuzz we hear so often in other equipment.  The sound is very engaging, wide band, dynamic, full range, and grain and grit free.
