T-KT88-GEN Vacuum Tube - KT88, Genalex Gold Lion
KT88 power tube reissue of Genalex Gold Lion. Made in Russia.
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.
