Linear Tube Audio MicroZOTL MZ2
Here is the MZ2 which started all the buzz about LTA. A 8 years continuing request for David Bernings "Blue Box" made LTA debut in 2015 with the MZ2. Here they released a revised version designed by Mark Schneider and David Berning. Now it is available in a Mk2 version and comes with different additions/options. The listed price is for the entry model: SMPS, No Remote, 2 ft dc cable and standard IEC mains power cable with Schuko or UK plug.

With linear supply: 8.94 lbs (4.1 kg) - amplifier and external power supply)
Finish: Aluminum case w/ lexan top
Tube complement per channel: 12AT7/6201 input, 6SN7 or 12SN7 output. (We supply NOS 12SN7 tubes by default. Jumpers on the circuit board allow you to easily switch between 12V and 6V, allowing you to use both 6SN7 and 12SN7 tubes and expanding your tube choices. The 12SN7 and 6SN7 are sonically identical and differ only in their heater voltage.) 12AU7 tubes can replace the 12AT7 tubes to lower the gain.
