Description
The Svetlana KT88 is a current-production beam power tetrode made in Russia’s Saratov factory — the facility behind many of the most respected valve types in production today. Svetlana’s KT88 features mil-spec internal construction, contributing to exceptional mechanical robustness and consistently reliable performance over extended service life.
The sonic character of the Svetlana KT88 is dynamic, controlled and authoritative — well-balanced across the frequency range with a particularly firm and extended bass response. These qualities make it equally at home in high-power Hi-Fi amplifiers and guitar rigs where the KT88’s clean headroom is valued.
Compatible with KT88, KT90, 6550 and similar positions. Popular in Marshall, Willsenton and Hi-Fi integrated amplifiers. Single valve, tested before dispatch.
