The VT-1 is the single channel version of the D.W. Fearn VT-2 Vacuum Tube Microphone Preamplifier.

In designing the VT-1 preamp, no compromise in sonic quality, reliability, or ruggedness was permitted. Like the best tube equipment of the 1950s and ’60s, the VT-1 preamp is built on a heavy-gauge aluminum chassis, utilizing point-to-point wiring. Each vacuum tube is selected for minimum noise and microphonics, and maximum sonic clarity. The front panel switches control sealed, gold-contact precision relays for all audio switching, eliminating the possibility of dirty contacts degrading the sound and minimizing the internal audio path. Four class-A triode amplifier sections (in two tubes) in each channel comprise the entire active circuit. This surprisingly simple circuit, along with top-quality components and careful design optimization, results in the sonic superiority that the VT-1 preamp has become known for.
