About the Fet Valve CFR
The Audio by Van Alstine Fet Valve CFR is a vacuum-tube stereo preamplifier designed as a flexible line-stage centerpiece for a hi-fi system. AVA currently lists it starting at $2,299, indicating this is the CFR model and not the older CF version. The preamp is based on an all-tube signal path with 12AT7 gain stages and 12AU7 cathode followers, while transistors are used only in the power regulation circuitry. It offers multiple analog inputs, dual main outputs, a tape loop, and a front-panel headphone output, with optional phono, remote, buffered tape out, and home-theater bypass configurations available on some versions or at order time.
