The new KR VA 200 monoblocks with the KR 842vhd tube application from KR Audio will be presented at the Melia Hotel in Milan for the Milano Hi-End show, Saturday and Sunday, April 2-3, 2016 in the Turchese room by Mr. Luigi Bocca of LAB Audio Technology Amministrazione as a world debut before the official presentation at the Munich Hi-End show next month, May 5-8, 2016 Halle 4, U08.

The VA200 is a circlotron with a Lundahl C-core output transformer. The driver stage is equipped with a depletion mode MOSFET transistors. The circuit is fully symmetrical with a differential input stage. The output tubes 8 x KR 842vhd per chassis) are fully auto-biased so no further adjustment is needed after replacement.

The new VA 200 monoblocks uses not only the KR hybrid circuit with the solid state first stage and the 8 x KR 842vhd tube application per chassis in the second stage, but is innovative for the design concept of the circlotron circuit or floating circuit giving the listener 200 watts.
