Linear Tube Audio is proud to present the ZOTL40 Reference+ amplifier. A worthy flagship and the most refined manifestation of David Berning’s ZOTL design.

The latest iteration of LTA's EL34-based amplifier, the ZOTL40 Reference includes a new chassis, component improvements, and is supplied with Mullard NOS EL34s that take this 50 watt-per-channel amp to a new level.

The ZOTL40 uses Mullard EL34 tubes, one of the best midrange tubes ever invented, so it has very solid midrange and authoritative punch.
