Linear Tube Audio ZOTL 10 Mk2

The next generation of the ZOTL10, the Mk.II, has a beefy linear power supply. Designed with ultra-low noise Belleson regulators, the transformer is in a separate enclosure in order to ensure the lowest noise floor possible. The ZOTL10 Mk.II is an expression of EL84 amplification that is accurate, uncolored, and now at another level. 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. There are two inputs, one direct and one with a volume control. The standard unit has an Alps Blue Velvet volume control for those that are skipping the preamp.  The Alps pot is a very nice, respected volume control, but for those that want a remote and zero signal degradation, we now offer an optional remote stepped attenuator utilizing Dale 1% precision resistors. All ZOTL10 models are upgradeable to the new power supply.

Speaker sensitivity & room recommendation.

​

LTA amplifier owners have found great enjoyment using their amps with a variety of speaker outside of the below ranges. The below are guidelines, not rules. If you have questions about your specific speakers, chances are someone we know has tried them. Don’t hesitate to reach out with questions about your specific setup.

Critical listening environments: 90db sensitivity and above

Smaller rooms / lower volume levels / non-critical listening: 88db sensitivity and above.

Also, don’t forget we have a 14-day no-questions-asked return policy.
