Well, there is no way to quickly flip a switch to do an "A-B" comparison of old vs. new tubes, however, I recently bought a Sebago Sound DT-50 amp that had the original 10 year old tubes. Lots of crackles and microphonics ... the builder, Bill Dunham, recommended the Tung-Sol tubes. Put in two new power tubes (6L6) and six 12ax7 preamp tubes. I chose the options of high output with low microphonics. Voila! This is now the quietest all tube amp I have ever heard. Kudos to Tung-Sol AND to Sebago Sound amps!

Ordered this tube in a kit for a Peavey Classic 30 and they sound great.

Great tubes. Clean and low noise but break up when you need them to.

Has a very clean and smooth sound with pleasant harmonics in V1 of a USA-built Peavey Classic 30. "Touch" is linear with predictable break-up with volume knob or harder playing. Back to buy another for my Zoom G5 pedal now.

I love the reissue tung-sol's. They have low noise and superior tone in the V1 position of all my amps. Also put it in the phase inverter position and works great in that application as well. Highly recommended!

Super fast shipping. Love the option to order balanced triodes for the PI tube. These are standard Marshall issue.

Got a pair of these for my Traynor YGL1. Nice and clear, no noise. Definitely an upgrade from the stock (Ruby branded) JJs.

I replaced the 3 stock JJ ECC83s in my Frenzel head [modified Tweed Deluxe circuit] with Tung-Sol. Main difference I notice is less preamp hiss at high gain settings [I specified low noise option], but also get a sense of more clarity across the board. The JJs had been in use for several years of home studio use, so I will have to compare longevity of the new tubes.

I was looking fora v1 tube to tame the highs and add some warmth to my Vox AC10 and the Tung-Sol 12AX7 seems to have gotten me much closer to that.

Great in the first position of my Peavey Classic 30 along with the Sovtek 12ax7LPS in the 2nd. Fat clean tone, headroom and musical tone. The combination improved the sound of the amp.

I've used every new production tube make in my many amps . The current TungSol 12ax7 is by far the best quality out there . The highs are clear and clean an the entire sound is transparent compared to a JJ . Yes , they're somewhat more expensive , but for V1/2 in a clean amp they are unbeatable , Tubedepot will provide every possible grading option too , which others don't .
Matched sides for push-pull , low noise/micro for higher apps and vibration , plus high-gain for gas-heads . Well worth the cost .

I installed a set of these in a Orange Dual Terror. The first thing I noticed was how dynamic they were. Soft picking or finger picking yielded a clean sound, as I dug in with a hard attack, the gain followed. They are nice and crisp, very articulate and loud. In comparison with the original jj tubes that came with the amp, the jj's yielded a fuzz type gain but almost no articulation. No matter how softly I would pick, it just wouldn't clean up. Could have been that the jj's were tired, dont know.
I'd suggest these if you're looking to tame your terror, make it more articulate but retain the gain.

Can't beat the Tung-Sol in just about any preamp position. I totally concur with this being the best of the best new manufactured tubes!

Tung Sol is my favorite brand of new manufactured tubes.

Nice tube the sound is actually way better than the Ruby it replaced. Will get more of those in the future. ;)

Worth the purchase! Bought 3 for a 1979 Marshall JMP 2203 (replaced JJ's) and loved the sound I was getting! Seem to make the presence of the guitar strings a bit more clear and much more gain than the tubes before. I highly recommend them!

Great tube, running with GT in V1, JJ in V2, TS is in the driver's seat. Lovely warm yumminess.
