Manufacturer's Description:

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 SED 6550C is an ideal replacement for amplifiers with GE 6550A tubes.
