D. W. Fearn have crafted the VT5 which is a high end vacuum tube stereo equaliser.

D. W. Fearn VT5 Vacuum Tube Mic Stereo EQ

The VT-5 Stereo Equalizer is a dual-channel version of D. W. Fearn's acclaimed VT-4 LC Equalizer. The frequencies, steps, curves, etc. are exactly the same. The VT-5 is a true stereo equalizer, with one set of controls that work on both channels simultaneously. It's smooth and sweet, and can be very subtle at mild settings, but quite strong with aggressive use of the controls. Creative use of the low boost and cut will create a powerful bass that has to be heard to be believed. The high boost adds just the right brightness to vocals, guitars, any sound, or even an entire mix. Even with extreme settings, the VT-5 will never sound harsh.

This stereo equaliser uses passive LC circuitry with class-A triode vacuum tube stages for the input and output. The tube circuitry is largely derived from the VT-1/VT-2 microphone preamplifier design, so the equaliser has much the same sonic character as the preamps. The LC-style passive equalisation circuitry is based on the classic designs that are still the best-sounding way to achieve high-quality tonal control.

The inputs are line-level, transformer balanced-bridging. An active vacuum tube input section has adjustable gain to accommodate input signals as low as -10 dBm. The input transformers are made by Jensen. The output stage utilises the same custom Jensen transformers used on the VT-1/VT-2 microphone preamplifiers. All controls are stepped for precise repeatability and uniform matching between units. High-quality rotary switches are used with 1% metal-film resistors. All of the audio capacitors are polystyrene or polypropylene. The inductors are custom-made for us by Jensen Transformers Inc.

The equaliser is constructed of heavy-gauge aluminum, with a a 3RU (5.25 inch), 1/4-inch thick front panel, finished in D.W. Fearn red. It matches the VT-1/VT-2 series of microphone preamplifiers in appearance and construction. Like the VT-1/VT-2 preamplifiers. The equaliser has been designed to provide an exceptional tool for audio professionals. The design frequencies and curves were determined by ear, after extensive listening to a variety of program material, both individual tracks and overall mixes. The result is a highly-musical equaliser with plenty of range for enhancing any track or mix.
