Electro-Harmonix's 6550 EH (Single)
Tubes by Electro-Harmonix
The choice of vacuum tubes in a tube circuit can make all the difference sonically. We have long experience in “tube rolling”, and access to the finest sounding new and new-old-stock (“NOS”) tubes available. On this website we list only the most popular, mostly new production, vacuum tubes, and also special finds like the amazing 6H23N-EB Russian military tube, which is a drop in replacement for 6DJ8/ 6922/ 7308 types. Please let us know about your actual tube components for a consultation on these listings or NOS tubes.
The perfect match for the Tung-Sol original. The 6550EH offers excellent linearity, power handling capacity and heat dissipation. Four-pillar construction and mica spacers help maintain a rugged mechanical reliability. Classic tone is sustained at a prolonged, high output. A new leaded glass compound is utilized to maintain vacuum integrity, balanced performance and ensure long life. Great tube for SVT and SUNN amps as well as all Hi-Fi amps.
