The next generation of the ZOTL10, the Mk.II, has an entirely new, linear power supply. Designed with the same ultra-low noise Belleson regulators as our MZ2's LPS+, we've put the transformer in a separate enclosure in order to ensure the lowest noise floor possible.

A redesigned backplate features WBT binding posts, copper RCA jacks, separate inputs allowing either a direct-to-board connection or the use of a volume control. After extensive listening, we've reconfigured the output wiring to improve the sound and shortened signal paths whenever possible. 

(Available very soon!) An optional microcontroller-based stepped attenuator volume control allowing attenuation with minimal signal degradation. 

The ZOTL10 Mk.II is an expression of EL84 amplification that is accurate, uncolored, and now at another level. 

All ZOTL10 models are upgradeable to the new power supply: visit the upgrade section on the product page. If you're interested in further upgrade options, contact us via email.

Designed by David Berning, the ZOTL10 Mk.II uses his ZOTL technology, which allows for a highly reliable protection circuit, low output impedance, very consistent performance regardless of speaker impedance, and low heat operation with long tube life.
