Product Information

  JOTA
  Art Audio > Amplifier (Tube)

  • Zero feedback design, high peak current delivery
    Automatic biasing circuit
  • Dual-mono design on a single chassis
    High quality mil-spec, multi-layered 2 oz. copper trace circuit boards
  • Output tubes mounted on a special isolation plate assembled with vibration dampers to acoustically isolate them from any chassis vibration
  • Employs a tube (CV-378/GZ-37) choke regulated power supply preceded by a pi filter and primary solid state rectifier
  • Capacitors are low ESR/ESL types for increased high frequency performance
  • Resistors are 1% metal oxide for low noise
  • Output transformers are a novel split core type not normally associated with single ended designs and custom-designed by Art Audio to give a wider bandwidth than most generally available transformers
  • Tube sockets are ceramic with silver plated pins
  • Finished with polished (non magnetic) stainless steel chassis, gold plated transformer caps and nameplate

High Power option

  • employs KR 52BX output tube instead of the stock VV32B
  • employs larger transformers and adjusted internal parts values to support the increased demands and current delivery (can also be outfitted with KR VV32B - however, the opposite is not possible - substituting 52BX for the VV32B in the standard Jota)
