KT88 BEAM POWER
TETRODE
The Svetlana™ KT88 is a beam power tetrode having
a large standard octal base and glass envelope. With a gold-plated molybdenum alloy grid and carbon-coated screen grid, the Svetlana KT88 is the finest power tube of its type being manufactured today. Its exclusive screen-grid radiator fins reduce a major source of failure in audio amplifiers, especially when operated in ultralinear or triode connection. All ratings of the Svetlana KT88 meet or exceed those of the original version; top-quality cathode materials and extensive aging yield outstanding performance in high-fidelity amplifiers. The Svetlana KT88 is made exclusively at the Svetlana Electron Devices factory in St. Petersburg, Russia, and is marketed worldwide by PM Components Ltd. and in the USA by PM of America Inc.
