D avid Berning is considered to be one of the world's most respected amplifier designers. 20 years ago, after 20 years of designing and manufacturing tube amplifiers, Berning turned tube amplifier technology on its ear: In 1996 Berning invented the the ZOTL (Zero hysteresis Transformer-Less) architecture. Radically different, it was and is still considered the most significant improvement to ...

In my book, a new product introduction from the creative mind of David Berning is an event, a happening if you will. ... The user manual outlines the performance of the amp with various tube types. With the stock tube complement, the feedback is highest, resulting in the lowest output impedance (about 0.6 ohms for an 8-ohm load). The use of ...

The ZH270 is a tour-de-force with respect to operation and internal protection circuitry. It uses two 6JN6 tubes per channel for power output and two 12AT7s and one 12AV7 tubes per channel for input and driver duties. Per the manual, the power tubes could last as long as 20,000 hours, driven gently.

Aug 23, 2011 . Berning provides a table in the manual explaining how to attain the various values. I swapped the AX 7 input tubes twice, initially for a pair of NOS (new old stock) Telefunken 12 AT 7s (ECC 81) and then a pair of Siemens 12 AT 7s to reduce the feedback levels to better match the Raidho Eben C1, C2, Focal Diablo and Kiso HB1s I was using throughout the 4 month listening period.

The microZOTL Preamplifier is based on David Berning’s patented ZOTL technology, the only advance in tube technology since the 1950’s. For a technology to be patented, it must be deemed “new, useful, and non-obvious.” We think that sums up our approach quite nicely.
There are three settings: 0db (default), -15db, and -30dB. You heard us correctly. The MZ3 is an end-game headphone amp, reference-level preamplifier, and an integrated amp that will drive sensitive speakers to thundering levels in critical listening environments.
It turns out that the theoretically correct turns ratio for most tubes is typically 100 to 1 and even as high as 300 to 1. The ZOTL can use the impedance converter to effectively create the ideal turns ratio. The microZOTL has a 300 to 1 ratio and the ZOTL40 has around a 150 to 1 ratio.
A formally trained physicist, David’s unique perspective has invaluably colored every solution he’s designed for classic audio problems. After 20 years of designing and manufacturing tube amplifiers, David Berning turned the technology on its ear when he invented ZOTL (Zero hysteresis Output Transformer-Less) architecture in 1996.
