6C33C-B Triode Output Tubes with Fully Balanced Signal Path

Delivering 55 watts per channel, VK-80i uses four 6C33C-B triode output tubes for power delivery. They offer many times the current delivery of the 6550/KT90 tetrode tube variant used in most traditional tube integrated amplifiers. In addition to driving even difficult low-impedance speaker loads, the all-triode fully balanced design provides a natural portrayal of harmonic texture and instrumental timbre. Your recordings will sound more alive while simultaneously yielding greater finesse, grace, and inner detail.

“Fuse-less” Protection Circuit 

In the event an output tube becomes over-stressed, all you need to do is turn VK-80i off and on again to restore normal operation. That’s it. The elimination of internal fuses also contributes to a greater sense of ease and more natural reproduction of music. Also, the fuse-less protection circuit is combined with a world-class automatic-bias circuit that eliminates the constant need to set and readjust the proper bias of the output tubes. No tubes to bias. No tube fuses to replace.

Intelligent Auto-Bias Design Makes Operation a Cinch

The advanced engineering within VK-80i eliminates the traditional headache associated with most vacuum-tube power amplifiers—specifically, the constant need to set and readjust the proper bias of the output tubes. VK-80i features an intelligent automatic-bias design that adjusts for changing line voltage and aging tubes, with each output tube having its own dedicated bias circuit. The auto-bias circuit also ensures your VK-80i sounds wonderful within the first few minutes of listening.
