The Svetlana KT88 is an excellent choice for users looking to upgrade their current KT88 tubes. This tube is a glass envelope beam power tetrode. It is intended for audio frequency power amplifiers. High plate dissipation, close manufacturing tolerances, and thorough processing provides improved reliability and superior sonic performance.

The Svetlana KT88 is manufactured in the Svetlana factory in St. Petersburg, Russia, and is designed to be a replacement for any KT88, KT90, KT99, or 6550.

Features

  • Greatly enhanced sonic performance
  • Increased peak cathode emission from the new cathode materials
  • Stable operation from extended processing and aging
  • Gold-plated grid
  • New tri-plate anode
  • Single piece beamforming electrode
  • Precise grid/screen alignment
  • Improved vacuum processing
  • Comprehensive static and audio amplifier testing before and after aging

“Svetlana tubes are quite simply the absolute best. We design and manufacture our tubes, engineered for demanding high fidelity, reliability and overall warmth. Be sure to insist on genuine Svetlana vacuum tubes the next time you retube -- you'll be getting the absolute best possible tubes for any demanding application.”
