This mighty fine beast is the EMT JPA 66 Mk II Varia-Curve Tube Stereo Control Center. That’s sort of a long winded way of saying it’s a preamp with integrated Phono stage. The JPA 66 offers an all tube signal path from input to output, employing only dedicated Audio-Triodes. It accepts 4 Phono- and 2 line level inputs. Outputs are fully balanced and floating on XLR or single ended on RCA. Almost every type of record pressings (vintage or most up-to-date, Mono or Stereo) can be compensated easily, rapidly and correctly. And the JPA66 can be used with virtually any phonograph cartridge.
