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 * x KR 842vhd per chassis) are fully auto-biased so no further adjsutment is needed after replacement.
The new VA 200 is a 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 with the same KR dynamic and precise KR signature sound with very much more power output.
The new KR VA 200 monoblocks with the KR 842vhd tube application 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. Luigui 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.
