Octal power tube (Max Plate Watts = 25W)

KT77 is a beam power pentode with octal base. It can be used in most EL34 amplifiers. It has more power, fatter bass and more headroom than the EL34 and E34L while providing very detailed tones.

I was a little skeptical about the difference from switching from el34s to kt77 and the tones I would get. After installation I was blown away! It was way beyond my expectations. Very saturated tone with a better low end. I couldn't be happier!

I put these in an Egnater renegade amp instead of the EL34"s and re-biased. Very clean with some upper end "jingle" that I did not have with the other tubes. Slightly more gain than the 6L6's and a little brighter. The tube matching with the new Apex system was dead on. Thanks again!!wb
