Model One

Features:

  • The push-pull output circuit uses Telefunken EL84-TK tubes that have been Cryogenically treated for extended reliability and tube life and come as a matched quad.
  • The input circuitry formerly used the hard to get NOS 7247, and these have since been replaced with the more readily available JJ ECC832 (12DW7), with gold pins.
  • A new power supply board uses solid-state silicon diodes for rectification and replaces the twist loc capacitor can, with four individual capacitors, rated at 105* centigrade each, and these upgrades far exceed the original in quality and reliability
  • This new power supply has an Enhanced Fixed Bias circuitry (manual adjustment required) to obtain lower bias currents for extended output tube life.
  • The Enhanced Fixed Bias power supply board achieves increased power output, both channels driven; and lower distortion overall.
  • The output tube sockets are Belton chassis mount sockets (4 each), using phosphorous bronze pins with tin plating.
  • The input tube sockets are Belton PC board mount sockets (2 each), using phosphorous bronze pins with gold plating.
  • Input RCA connectors are Cardas CTFA, brass base with silver/rhodium plating.
  • Output binding posts are Cardas ACBP S, high purity copper base with silver/rhodium plating.
  • Power Entry Module (PEM), rear mounted to chassis, with power switch, fuse holder and IEC connector for detachable power cable.
  • 21.5 AWG, Cardas chassis hookup wire for signals.
  • 18.5 AWG, Cardas chassis hookup wire, for ground buss and heaters.
  • Various types/sizes of stainless steel screws, washers, loc washers and nuts.
