The JJ Electronic KT77 is a reproduction of the original tubes that captures the sound that made the KT77 famous. In their typical fashion, JJ has built this tube in a solid construction that is robust and highly reliable. This tube has more headroom than a typical EL34. The low end is fat and defines with detailed and responsive mids and smooth highs. This is an excellent tube for adding more power to the sound of an EL34 amp.

Excellent sounding tubes. Great bottom end response.

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
