JJ-KT77

    The long awaited JJ KT77 is here. A direct replacement for any EL34 / 6CA7, the JJ KT77 has a lot of power and headroom but is surprisingly refined sounding. We love this tube in Marshalls and for any Hi-Fi application using EL34 / 6CA7.




    • Love this tube in my Orange OR50!

    • Used these tubes in my custom push pull class A amplifier. Sound pretty nice, very clear mids and trebles. Happy with this purchase.

    • Been using these for years in my 100 watt Marshall's. Mainly the TSL-100. Will try them in my JVM410h when they need replacing. Really adds bottom end and smooths out the top end.

    • Very lively and thick sounding tube. Really like the JJ KT77 in my 50watt Epiphone head.

    • I love these tubes! Soundstage is huge! 3D and air beyond compare! Running them in a Jolida 3502S with JJ E83CC and JJ ECC81 in the preamp and driver stages, the JJ KT77 sounds spectacular. I may never roll tubes again, they're just to amazing.

    • Follow-up from my last review. I just rolled the KT77s into my amp again and they are absolutely stellar. The soundstage is enormous and the 3D is totally awesome. They sound very powerful with a nice thump in the bass, crisp but smooth treble and solid midrange. I can't believe I let them sit on the shelf for months. I should have just left them in and not rolled any other tubes, Of all the EL34 type tubes I've had over the years, I really think the JJ KT77s are the best of the lot.
