ZOTL10 - A New Berning Amplifier

The ZOTL10 is first in a new series of hand built amplifiers designed by Mark Schneider and David Berning for Linear Tube Audio to be introduced Fall 2015.  Perfect for new types of high efficiency or full range speakers, the ZOTL10 produces a much lower hum than typical tube amplifiers, which can be much more pronounced when connected to high efficiency speakers.  Designed for medium to high efficiency speakers, the ZOTL10 uses EL-84, 12AT7, and 12AU7 Russian Tung-Sol tubes.  It will first be offered in a power amplifier configuration.  

The ZOTL10 has all the features that ZOTL technology brings:

  • Little or no hum
  • Incredible realism
  • Push-pull, Class AB output stage
  • 10 watts per channel
  • Premium Tung Sol Tubes
  • Transformer-less design eliminates intermodulation distortion inherent in all transformer designs
  • Impedance converters simulate correct theoretical output transformer turns ratio
  • Low impedance output easily matches wide range of speakers - cannot be damaged with no load
  • Autobiasing - no adjustments
  • Automatic protection circuitry
  • High voltage turn on delay to maximize tube life
  • Extremely long tube life (typically 10 years or longer)
  • Hand-wound coils & impedance converters
  • No heavy power or audio transformers
  • Universal voltage power supply (autosensing 100-240VAC 50/60Hz)
  • Power amp has one input through Alps volume control for direct connection to high output sources
  • Second set of inputs bypass volume control for direct input
  • One year warranty including tubes (international buyers pay shipping)
