> 3 dayPurchased 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.

> 3 dayI was replacing Tubes in my Amp too often. I was able to save money and these are still blasting.

> 3 dayI 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.

> 3 dayI bought these tubes for my Hot Rod Deville (4x10). They sound great in the amp but are a lot more quite than the original tubes (Groove Tubes). I will say its great because I turn get it to break up at a much lower volume and get that tube tone Im looking for without being way too loud (although it still gets plenty loud). Also these are not the technical tubes that should go in the amp. Technically my understanding is they hsould be 6L6GC tubes but these work and sounds great!

> 3 day[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.
