Description

If you have been waiting for an alternative choice for a 7591A, the wait is over. Measuring 3 1/8" high from the bottom of the base to the top of the envelope, the JJ 7591s is about the same size as the JJ GZ34 / 5AR4 and JJ 6V6. We like this tube for everything from HH Scott amplifiers to the few musical instrument amplifiers that use the 7591.
