Now in stock - the new JJ 6CA7 power tubes! The mids and low end are fantastic. Quite similar to 6L6 tone but with a little more rolled off high end.

From our review of this 6CA7 vacuum tube: "When installed in a 50W Hiwatt head these tubes just roar. It’s a classic sound for beefy rock anthems. The sound is firm and articulate. A number of customers have reported that this 6CA7 tube is darker sounding. Your mileage may vary but I found nothing dark about them at all. Smooth yes, dark, not so much in my testing."

JJ 6CA7 | Great


Once I put them in a Primaluna Dialogue premium intergrated for fun, and never took them out again. This JJ-6CA7 is the perfect tube for this amp, subtle and very balanced. The slightly rough edge of the Primaluna turns into a musical sounding amplifier for long listening.

JJ 6CA7 | You can't go wrong for this price.


Amazing JJ-6CA7 tubes for great beefy guitar tones when teamed up with a Marshall and Les Paul. You can't go wrong for this price.

Lots of tube, little price.


Excellent tube on a budget. I've paid more for less.

Clarity and frequency response are very good. Low end is robust and clear and the midrange is thick. As other reviews state, they are dark and are good for taming excessive high end. If you like lots of treble in your sound you may want to look elsewhere.

For $20 this tube is a rock solid performer. Good job JJ, money well spent.

Oh, what growl...


Fantastic tube if you have an amp/guitar rig with lots of high end that you need to tame, speaking from experience. Dark but still articulate. Great kick in the mids without being overbearing. A wonderful change for my ears.

Not a KT77


I bought a quad of the JJ 6CA7's to compare to the EH 6CA7 as well as the JJ KT 77 in my own personal "shoot out" of sorts. In a nutshell, I prefer the JJ 6CA7 over the EH as the JJ (to me) sounds a little more "full" in a expansive way. I also prefer the JJ 6CA7 over the EH in the midrange as I feel it is slightly more realistic, more "3D" sounding over the EH tube. But, between the three, the JJ and EH 6CA7 and the KT77, the JJ KT77 is the best of the three, being better in the highs, a cleaner midrange and just a better overall performer and the better value.
