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 www.theabsolutesound.com/articles/linear-tube-audio-zotl40-mk-ii-power-amplifier/

  • Uses 4 KT77s, 2 12AU7s, 2 12AX7s (can be used with EL-34s)

  • One year warranty including tubes (international buyers pay shipping)
