Product Details

The sound of the future—and the sound of musical truth

The empire-building VK-76SE features a completely revised power supply, fuse-less protection circuit, active current sources for its two gain stages, intelligent auto-bias circuit with LED indicators, and high-current, all-triode, zero-feedback, fully balanced topology. BAT realizes serious listeners want unique technology, user-friendly experiences, and faithful-to-the-source sonics when considering luxury high-end equipment. The equivalent of having two single-ended amplifiers per channel, VK-76SE meets these lofty demands and more—and sounds mesmerizing minutes after being plugged in. VK-76SE also means there are no tubes to bias. No fuses to replace. No pentodes imitating triodes. No direct current present at the tube output stage. VK-76SE is the sound of the future—and musical truth.

 

Active dual-stage current sources for improved linearity and accuracy

VK-76SE extends the advantages of active current sources to include both the first and second gain stages of the circuit design. There are multiple benefits to implementing active current sources (solid-state as well as tube) for the first two stages of VK-76SE. Specifically, the linearity of the gain stages improve; the adjustments for the first and second gain stages become independent and more easily optimized; and the active source components operate at much lower stress level, improving reliability. The final result is an impressive improvement in the linearity, yielding a more accurate representation of the output signal to the original input signal. That, in essence, is the measure of any amplifier.

 

Fully symmetrical, all-triode circuit banishes conventional drawbacks

In a world of cookie-cutter pentode/tetrode designs and frail single-ended counterparts, VK-76SE is uniquely different. Its design is fully symmetrical from beginning to end. You can think of it as two single-ended amplifiers per channel, with their waveforms summed at the output transformer. Since no direct current flows through the output transformer, the latter is truly a wide bandwidth design that also reduces low-frequency distortion. When you combine VK-76SE’s fully symmetrical circuit with its high-current, all-triode, zero-feedback, fully balanced topology, all of the drawbacks of push-pull and single-ended amplifiers are banished.
