        An amp expert in Seattle recommended JJs. I replaced the stock Sovtek tubes in a Carvin Vintage 16 with a matched pair of JJ EL84s in the power section and JJ 12AX7s in the preamp. The difference is impressive: The somewhat harsh tone of the low-end Sovteks has been upgraded to a rounder, fuller tone. With the V-16's "soak" control on 8 or 9 and a Tube Screamer driving the input, it's easy to dial in a Marshall-like tone.

        Overall it reminds me of the old Telefunken tubes. Great highs and mids, and when driven to it's limits the distortion break up is even and dirty!
        I love JJ tubes, and this little guy is not an exception. I replaced the unknown tube in my Blackheart 5W head with this tube. You can get the shimmery highs, swirling mids like a Fender/Vox, while the bass can crunch right up there with a Marshall. Highly recommend this tube. It's a great little workhorse as well!
        No pops, crackles or hisses. And even with the abuse one gives ones amp gigging, it still pulls through!
        Not as pricey as the NOS tubes, or as the groove tube el's. Very good buy!

        Comments about JJ Electronics EL84 Power Vacuum Tube:

        This was my second Blues Junior I used these to replace the stock tubes. Result: smoothed some of the known harshness and refined the overdrive a bit. The first time the Groove Tubes were slightly worn so made a huge difference. The second amp, the tubes were very low hours so a better comparsion. Both times, tone improved, less harsh and overdriven had a more usable crunch than the stock Groove Tubes. Not a huge change but enough to be worth the trouble.

          To my ear these sound every bit as good as the GTs at nearly half the price. The JJs will go into all of my amps in the future.

                Comments about JJ Electronics EL84 Power Vacuum Tube:

                I have a VoxAC15 that I purchased several years ago. Was happy with sound, but then I heard about upgrading tubes to augment tone. So I took the plunge and first upgraded the tubes in the preamp section, and the difference was quite noticeable. Several months later, I decided to upgrade the power tubes to JJ EL84s, and am completely blown away with how much impact they have on overall tone and response! It is like a blanket has been lifted off my amplifier! The cheap stock tubes that came with my amp were impeding this amp's tone! I heard about this amp's "chime", but am only now truly experiencing what that truly means.

                      I mostly play through single stroke class A amplifiers with no frills. Having a good quality tube really stands out. The JJ Tesla's seem to be the better tube considering the fact that there are only 3 manufacturers making tubes. Went through several pre and power amp tubes recently relatively quick.Switch over to JJ Teslas and have had no issues. Full, thick signal with no noise.
