ZOTL40 Mk. II POWER AMPLIFIER

Linear Tube Audio and David Berning have produced the ZOTL40 Mk. II. A worthy flagship and the most refined manifestation of Berning's ZOTL design. The ZOTL40 Mk. II Power Amplifier provides 40+ watts per channel with accurate, uncolored sound and automatically protected circuitry.

The Mk. II version incorporates KT77 tubes and a few other component changes to make this great amp even better.

FEATURES

  • Designed by David Berning
  • Hand-wound coils & impedance converters
  • 40 watts per channel with little or no hum
  • Frequency response flat from 8Hz to almost 50Khz
  • Transformer-less design eliminates intermodulation distortion inherent in all transformer designs
  • Impedance converters effectively produce theoretically ideal output transformer turns ratio
  • Low impedance output easily matches a wide range of speakers and cannot be damaged with no load
  • No adjustments – tubes are auto-biased
  • Automatic protection circuitry
  • High voltage turn on delay to maximize tube life
  • 10 - 20 years tube life depending on use
  • Push-pull, Class AB output stage
  • No heavy power or audio transformers
  • Berning-designed, custom universal voltage power supply (autosensing 100-240VAC 50/60Hz)
  • Has one input through Alps volume control
  • Second set of inputs bypass volume control for direct input
  • Uses 4 KT77s, 2 12AU7s, 2 12AX7s
  • One year warranty including tubes (international buyers pay shipping)
