Electro-Harmonix's KT90 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 Electro Harmonix KT90 is a great sounding tube. The low end is not boomy at all, but quick and responsive. Female vocals will be noticed with tube. Very realistic mids with a sweet top. Highly recommended.
