      Read complete review

      This tube is unique among the current production 6V6 offerings. This can be good or bad depending on your needs. To me, it's a very good thing for two reasons.

      1. Rugged build. The JJ 6V6S is a very robust tube with it's rugged construction and spiral filament. It is widely reported that the JJ's can take higher voltages than the others. This is a very good thing when installed in my Tweed Deluxe clone or a Deluxe Reverb. Those amps are especially hard on power tubes. While I love the sound of the Tung Sol Reissue tube, for example, I do NOT love having one blow after a month or so of service. This has happened to me twice. Maybe just a bad batch, maybe not.

      2. Sound. The JJ tube is a little bigger and the sound is a little different than the other current production 6V6 tubes, a little more 6L6 like, as others have stated. If you are a stickler for vintage correct 6V6 sound, then this is probably a bad thing. But it is an especially good thing for me in my Tweed Deluxe clone ( only 12 watts), especially on a gig. The JJ 6V6S tubes are a little bigger, bolder and more aggressive sounding than the other offerings. They cut through the mix a bit better. They break up a bit later and stay more clear when overdriven, with a little less of the mushy compression that is characteristic of the 5E3 circuit. In addition to going to a more efficient Celestion Blue speaker, the switch to the JJ 6V6S tubes has helped my 5E3 Deluxe make the transition from bedroom/studio to the gig. I love that.

      I purchased 2 separate JJ 6V6's for use in my single ended class A amplifier. The stock Ruby tube sounded OK and I tried EH tubes which sounded even better. I decided to try JJ's because I'd heard they were better built and more robust than the others. WRONG. Both JJ's failed within 10 minutes of use. The amp is new and biased correctly for 6V6 tubes. The JJ's each made a crackling sound and fizzed out in the same manner. I won't buy JJ power tubes again. I've had good success with their preamp tubes.

            Comments about JJ Electronics 6V6 Power Vacuum Tube:

            This is a super tube. It is not a 6L6 (of course) and it is not an EL84 (of course) and it is not really a normal 6V6. It is really different than any other tube out there.
            You should really bias your amp or have someone bias it as I would not just drop this tube in as a replacement for any other model 6V6. Oh, it would probably "work," but not at its optimum performance. It is a larger tube that takes more plate voltage than a typical 6V6 tube. To really make this baby sing like it does you need to set the amp up for it. It is a wonderful, sweet sounding tube. BUT...bias your amp accordingly. Also keep in mind that this tube set up is for 8 ohms output (as is typical of 6V6 tubes). If you have an amp that will run at 4 ohms and want to switch to this tube you should consider a dummy load of sorts on the transformer. Once again, "it will probably work," without doing that, but not at optimum. If you have an amp that currently runs 6V6 tubes, you need to set the bias on the amp to compensate for the different plate voltage and make the tube sing for you. If you want to use this as a replacement tube in an amp that runs 6L6's (unlike other 6V6's this one will probably work in that format) you can probably get away with it. BUT you must bias the amp for the tube switch and adjust the transformer output for the 8 ohm output impedance difference. Just my 2 cents worth.

              I replaced the original 6v6 electro harmonics tubes in my 7 yr old Super Champ XD,,although the sound changed a bit it is a enjoyable change.

                      SNAKEBITE, I think your problem started with rebiasing your amp. I'm not sure what the Plate Voltage on your amp is, I think it's close to 410V. Most amps running 6V6's the bias should be around 19 to 23 mA. I think what you did was over stress the B- plates its no wonder the tubes are failing. Infact I'm supprised either tube is still working. A true testiment to their quality. Please rebias you amp closer to factory specs and then try again.

                      These tubes were suppose to be a "Matched" pair. I put them in my Fender Super Champ XD, and set the bias to 40 ma. Things start out OK, but after a good Rif, one of the tubes starts drawing too much current and gets Red Hot while the other tube does not. It doesn't matter which socket it's in, the same tube takes off when playing through the amp. I can't even use them!

                            I got about 500 hours out of this same tube before it started going out (making random noises). So that's about a year for me. I use it in a VHT Special 6 (one power tube), so for me changing the tube once a year just before our church Christmas program is easy to keep track of.

                            The sound of this brand was better (in my mind) than the stock tube.

                            This tube really cleaned up the sound for my little Fender Champ 600. Not that this amp pushes sonic extremes, but it certainly help give the Lil' 600 a clean, brighter distortion in the higher registers of volume. Sounds really good with my Russian EH BigMuff, too!

                                  I bought these to replace a pair of E/H that came with a Fender Super Champ XD from 2007. One of the E/H was arcing.

                                  JJ is sort of a standard in tubes, and I could see no harm in buying a matched pair.

                                  The amp is a wee bit stronger now, maybe. All the "amp sound" in the Super Champ XD is really in the preamp ( the power tubes are said to not be pushed all that hard ) so so long as they can be clean, they seem to work. The E/H were a bit underbiased.

                                  This amp may have had a marginal contact from the digital board to the rest of the amp - there's a dual row connector ribbon cable from the digital board to the rest of the amp. When I reassmbled the amp, it made no sound and would not repsond to controls. I used contact cleaner ( Caig ) to clean this, and haven't had trouble since. I have to wonder if what I thought was tube arcing wasn't a marginal contact from the digital board - the E/H seem to work fine as well.
