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

When I bought these, the marked price was about 30% lower than today, so they were a great bargain. Id still buy them at todays price, too. JJ are a great tube brand; Slovakian-made in the former Tesla Electric factory (they cant or dont use that name any more).

Great tubes. Running a lot of JJs these days!

what can I say, these work great. My NOS RCAs burned out due to a power surge These sound good

Product as advertised shipped fast!

Put new life in my Deluxe reverb amp!

The Yellow Jacket Triode configuration works exactly as described. Installation was about 3 minutes. These tubes tame my Randall RT2/50 power amp and allow me to have power section saturation without blowing my windows out and getting the neighbors on the phone to the cops. The resulting sound is full and ballsy, but at at a reasonable volume. With very efficient speakers (say Celestion Blues or other alnicos like Ted Webers) this throttled-down power section will still give a startling amount of volume, so the YJS triodes wont relegate your amp to the bedroom. Perfect practice volume, and maybe enough for a small club. Highly recommended.

I got confused if I had ordered a pair or a single tube. Called the seller. They were very helpful. This is a matched pair as indicated by the MP. Used them to replace the 6L6s in a Fender Hot Rod Deluxe. They work and sound great!

works as expected sound is also great

Got these to replace the old tubes in my Egnator Rebel 30 and brought it back to life. My old tubes were rattling bad and these are much better, they dont seem to rattle much at all. I also got the EL84s and 12AX7s from JJs too, Huge fan.

[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.
