The Fet Valve CF RB is our best all tube preamp that will appeal to audio purists embracing minimal setups, and anyone looking for astonishingly detailed and musical tube sound.

With the Fet Valve CF RB, we have taken everything we know about getting tubes to work as well as they possibly can and rolled it into a minimal yet functional package. We have packaged these stunning circuits into a reduced feature chassis that will serve the needs of audio purists and budget sensitive audiophiles.

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

 

 

AVA has long been an advocate of rock solid power supplies, and the power supply used in the Fet Valve CF RB 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 RB power supplies are incredibly quiet and rock stable platforms on which our audio circuits can perform their best.

Our goal with the RB chassis was to eliminate all functions that audio purists don't use. This significantly reduces the parts and labor costs, but does not compromise the audio quality, and allows us to offer uncompromising sonic beauty at a much lower cost than you would ever expect.

The RB Chassis has a precision volume control, four sets of line level inputs (with one input being used for the optional phono section, if specified) and two sets of line audio outputs.The aluminum 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.
