In 1957 Marconi-Osram Valve Co. (Genalex) introduced the “King of Power Tubes”, the legendary Gold Lion KT88. This tube became the heart and soul of such classics as the Dynaco Mark III, McIntosh MC275, and Marshall Major. Unfortunately, Genalex ceased tube production in the early 1980s and the Genalex Gold Lion KT88 has become very expensive and hard to find.

After extensive research and engineering, New Sensor Corp. has reissued the famed Genalex Gold Lion KT88. This tube has been recreated down to the finest detail with gold plated grid wire, carbonized screen grids, and a tri-alloy clad plate structure for exceptional performance and sound quality.

Our Emerald amplifier is a stereo amplifier using 4 Gold Lion KT88. The prototype has been running tests for a couple of months now, so it is expected to be in production second or third quarter 2013.
