KT88 SVETLANA~~The Svetlana KT88 is a glass-envelope beam power tetrode. It is intended for audio frequency power amplification service. High plate dissipation rating, close manufacturing specification 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 direct replacement for any KT88, KT90, KT99 or 6550. The new KT88 features greatly enhanced sonic performance: Increased peak cathode emission from new cathode materials; Stable operation from extended processing and aging; Gold-plated grid; New tri-plated grid; New tri-plate anode; Single-piece beam forming electrode; Precise grid/screen alignment; Improved vacuum processing; comprehensive static and audio amplifier testing before and after ageing.~SELECT MATCHING|KT88-SVT|SINGLE|KT88-SVT-SINGLE|MATCHED PAIR|KT88-SVT-PAIR|MATCHED QUAD|KT88-SVT-QUAD|~2688~8683~~

Genalex - Gold Lion KT88~~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.~SELECT MATCHING|GT-KT66HP|GL - KT88 (SINGLE)|LION-KT88-S|GL - KT88 (PAIR)|LION-KT88-P|GL - KT88 (QUAD)|LION-KT88-Q|~2688~9583~GOLD LION, KT88, GENALEX, VALVES~

SOVTEK
6550~~The Sovtek 6550 were designed to be the finest 6550's ever produced. Thicker plates, improved heat dissipation, higher transconductance, and increased linearity are just some of the inherent aspects of the new Sovtek super 6550's. The resulting performance advantages include 5% higher output power, increased reliability, greater headroom, and superior tone.~SELECT MATCHING|6550-SOVTEK|6550WD (SINGLE)|6550-SOV-SINGLE|6550WD (PAIR)|6550-SOV-PAIR|6550WD (QUAD)|6550-SOV-QUAD|~2688~8687~~
