JJ Electronics Amplifier Tube (T-6V6-S-JJ-MP)

I replaced the stock tubes on a Fender Pawn Shop Excelsior with these JJ tubes. Excellent upgrade in tone.

I replaced the tubes in my Tweaker a few months back but everything I tried was microphonic and extremely noisy. Then I did some research. I have an early model Tweaker which runs a lot of current through its power tubes. Bruce Egnater himself recommended JJ 6v6s for reliability, and I can understand why. As soon as I put these in my problems disappeared.

As said by other reviewers these sound much richer than the OEM tubes in my VHT amp. Thanks to these tubes I actually love to hear the sounds coming from that amplifier

Garbage. Stopped working.

Put new life in my Deluxe reverb amp!

[Used in a Ceriatone Dumble Overdrive Special style amp substituting for 6V6gt.] Outstanding cleans: nice crisp highs and a bit more bass than I heard with my old-stock (other brand) 6v6gt tubes which had plenty of life left in them... just chalk it up to design differences? The new JJ tubes even have more clean headroom and theyre a little quieter at high volume = more on the top and bottom! That surprised me! The trans-conductance matching was perfect (confirmed on my own tube tester and in-circuit) and this let me dial the bias in right where I wanted it. This matching is especially important to avoid clipping from a tube that is out-of-range, otherwise youll compromise your bias setting with one tube too high and the other low. I set these quite a bit colder (19.5mv) than the prior set (straddling @ 24mv) but they JJs showed no signs of clipping on the oscilloscope and were pleasing to my ear. Note that these JJ 6v6s tubes are physically larger (longer/taller) than typical 6v6gt tubes by about 1 (2.2cm). For most it wont be a problem but if youve *very* tight clearances in your amp chassis it might be an issue so please be aware. Id rate this tube set + matching service six stars, if I could. Im tempted to buy a spare set now just to put them aside for the future.

Purchased for a VHT Special 12/20 head, and very pleased with the results. These tubes really opened up the sound, and generally you can hear/feel the extra punch now. I was looking to increase clarity/articulation, as this amp is known to be a little dark with some configs. While not as helpful as my EQ pedal, these tubes did, IMO, improve the overall quality of the tone. If I could A/B tubes easily, Ive absolutely no doubt in my mind these are superior to the stock tubes.

They arrived quickly and were just what I needed to fix my Vibro King amp. Theyre good quality and a great value. Thanks!

Ive got a set of JJs that came in a 69 Princeton Reverb I bought online. They sounded harsh and bright in that amp. I put them into an Excelsior and they sound pretty good, still bright and hard sounding, but the Eminence Legend speaker turns that sound into a nice quack/chime. They are louder than Tung Sols, bigger sounding and more texture than the TS or the EH. They pale in comparison to a good set of RCAs in any amp Ive put them in. RCA is THE 6V6 to have, but these will do.
