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.
