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)
