Karma-AV is bringing the BAT VK80i all-tube integrated amplifier to the UK. Incorporating features from the company’s flagship REX range including triode-balanced architecture, fuse-less protection and automatic-bias circuits seen in the REX 3 power amplifier. 

Generating 55 watts per channel, the VK80i uses the triode 6C33C-B tube, which offers many times the current delivery of the 6550/KT90 tetrode tube variant often employed by traditional tube integrated amplifiers. Arranged in a fully balanced topology, the 6C33C-B allows the VK80i to deliver the “high-current performance required to drive even difficult low-impedance speaker loads while providing a natural portrayal of harmonic texture and instrumental timbre”.

The elimination of internal channel and tube fuses means that the VK80i’s performance is not compromised by the quality of the fuse that is often placed in the signal path of an amplifier channel. In the rare event of an output tube becoming over-stressed, normal operation is restored by turning the VK80i off and on again.

Advanced engineering within the VK80i eliminates the need to set and readjust the bias of the output tubes. The VK80i features an intelligent automatic bias design that intuitively adjusts for changing line voltage and aging tubes, with each output tube having its own dedicated bias circuit. Typical UK pricing inc VAT: £9,995.00; availability: September 2021.
