Fully upgraded to MK2 status in summer 2016...including new boards and pure copper (not brass plated) speaker binding posts. Even more quiet and thus natural / dynamic than before! http://www.6moons.com/audioreviews/tomevans/lineara.html
Linear A is a hybrid, single ended, Class A, ultra-linear stereo amp with 25WPC. Four EL84 tubes per side, in parallel, create a composite tube with characteristics almost identical to the legendary Japanese No.10 tube.
