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 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)
