Know before you buy
The V4s are highly versatile and support EL34, 6550, KT88, and KT150 power tubes. This allows you to tailor the sonic signature of your system to your personal preference.
Each tube features independent bias controls and an integrated bias meter located on the chassis. This makes it straightforward to monitor and adjust your tubes for optimal performance and longevity.
The V4s deliver 120 watts per channel when using KT88 tubes and increase to 170 watts per channel when using KT150 tubes. Both configurations are stable into 4 or 8-ohm loads.
The amplifiers are designed to drive both 4-ohm and 8-ohm speakers effectively. You can select the appropriate output tap on the binding posts to match your specific speaker impedance.
The hand-wired, point-to-point construction is built for long-term reliability and ease of service. Because the design utilizes low screen voltage, you can expect an extended lifespan for your power tubes compared to more aggressive designs.
With up to 170 watts per channel and a peak power of 210 watts, these monoblocks provide significant headroom and dynamic range. They are well-suited for driving demanding speakers that require substantial current to achieve a full, three-dimensional soundstage.
