Jota

To us, the name says it all. Jota is a jubilant folk dance from Aragon, Spain. And like it’s dance namesake, the Jota was designed with an agile and honest 20 Wpc to get you moving.
The result: Superior sonic fidelity married with low-end control.
It’s been called the one single-ended amp to have if you could only ever have one. And that doesn’t surprise us given the attention to minute detail we lavished on this design.
A labor-intensive sub-assembly mechanically isolates the output tubes from the main chassis to enhance longevity. And the output transformers are our own hand-wound split core design that delivers dynamics and immediacy that sets this amplifier apart from its Class-A brethren.
We invite you to audition the Jota with your nearest Art Audio representative.

  • Zero-feedback design, high-peak current delivery
  • Automatic biasing circuit per each channel
  • 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 transformers generally available
  • Output tubes mounted on a special isolation plate assembled with vibration dampers to acoustically isolate them from any chassis vibration
  • A tube (CV378/GZ37) choke-regulated power supply preceded by a pi filter and primary solid- state rectifier
  • Resistors are 1% metal oxide for low noise
  • Capacitors are low ESR/ESL types for increased high frequency performance
  • High quality mil-spec, multi-layered 2-oz. copper trace circuit boards
  • Finished with polished (non magnetic) stainless steel chassis, gold or chrome-plated transformer caps and nameplate

High power options

  • EML 520 or KR 300BXLS output tubes instead of the stock KR 32B
  • Larger transformers and adjusted internal parts values to support the increased demands and current delivery (can be outfitted with 32B - however, the opposite is not possible - substituting 520, 300 BXLS for the 32B in the standard Jota)
