Re: Tung-Sol 12AX7
My 2 favorite 12 ax7 tubes are the EH and the TS (current prod that is).
The Eh are a tiny bit warmer to my ears than the TS but both are awesome, it just depends on the application. You'd be hard pressed to tell one from the other outside of an AB test in the same amp done quickly.

clearer and chimier than jjs.
Less midrange grind than EHs.

Re: Tung-Sol 12AX7
What amp are they gong into, which power tubes does it have, and which cab/speakers are you running it through?
I ask because Tung-Sols have proven to be too bright on top for certain setups for me. They are a nice vibrant, clear, and bright tube, though.

Re: Tung-Sol 12AX7
My preference new production tube, never had a chance to try NOS though. Great tone, bright but not harsh like the EHs I've tried, not buzzy like most of the Chinese ones I've tried. I've read that a lot of people have had premature failure and spotty Q/C with them, especially as cathode followers, but I've never had one fail in the nearly 10 years I've been using them, and that's in every position In the amp.

Currently using the standard 12ax7 in my Tubemiester, gold pin variant in my JCM 900 and MkV boogie. The Boogie also has Tung Solar EL34Bs, the Marshall has their 5881s, and my Hot Rod Deluxe has their 6L6GCs

Re: Tung-Sol 12AX7
I think it's a great V1 tube, and I agree with almost everyone in the thread. I pair my V1 TS with a Chinese 12AX7 AC5 HG+, which fills out a bit more of the lows and low mids. I have had the TS fare pretty poorly in the PI position, though, as far as lifetime goes, and that's the only place I'll tolerate a JJ, and even then only a long-plate ECC 803S.

I like Tung-Sols and they're one of my favourite tube brands. I find them clear and lively.

Re: Tung-Sol 12AX7
I have a couple around, and I bought the 12AX7 sampler set (https://www.amplifiedparts.com/products/T-12AX7-SET), and I have some NOS laying around.
My comparison point (holy grail) for the best V1 12AX7 for me (and I'm a classic rock/vintage guy, not a shredder, so take that into consideration) is an original International-branded Mullard 10M that I have. Given that as the grail, this is my list in order.
(This group is smooth and sounds closest to my Mullard 10M, the TAD sounds exactly like my Mullard 10M)
1. TAD Tube Amp Doctor 12AX7C-PS
2. Ruby 12AX7A-C5
3. JJ ECC803 long plate
(This group sounds pretty good, but starts to have brittle/piercing/bright top end for me)
4. Groove Tubes 12AX7C-GT
5. TungSol 12AX7
6. JJ 12AX7S-JJ
7. Mullard 12AX7/ECC83 (Russian reissue)
8. Electro Harmonix 12AX7-EH
(Right here they get harsh and almost unusable for me)
9. Shuagang 12AX7B
10. Sovtek 12AX7A-WB
11. Sovtek 12AX7A-WA
I tested these in a Marshall JCM900 / Marshall 1960AV; a custom, boutique, hand-wired JTM45 / Marshall 1960BX; and an Emery SuperBaby / Randall-Celestion 1/12; using a 1994 Gibson Les Paul Standard
FWIW - interesting comparison chart of 12AX7 tubes

Re: Tung-Sol 12AX7
This IS a Gear Forum, but.....do not let 20 bux stop you from buying and trying.
Like with, speakers, strings, guitars, amps, pedals, etc etc .....it all changes with the application/situation.
Just be careful where you use it.....Cat Follower and Phase Inverter will usually exceed the Heater to Cathode rating of those tubes. LOTS of failures in V2 of the typical Bassman/Marshall circuit.
good luck

Re: Tung-Sol 12AX7
I have had failures of the TS reissue in V1 of my Marshall Jubilee. Same failure mode as EH 12AX7s in V1 in the same amp. I use them in V1 of other amps with out problems but my Jubilee just kills em. I don't have any problems running NOS or even Chinese tubes in V1 of the Jubilees though. I currently run a NOS American Sylvania 12AX7. I also have an Siemens ECC83 that is a bit noisey but works and has great tone in the Jubilee.
I liked how the TC sounded, and I like how it sounds in my other amps, but they are not reliable in the Jubilee.

Re: Tung-Sol 12AX7
I've never tried TSs in my 2555, but I've run EH 12AX7s since late 2001 and I've had great reliability except for a couple DOAs.

Re: Tung-Sol 12AX7
IME: great tubes for "controlling" the mushiness that low headroom amps can suffer from. They're good to use if your gig calls for turning up your 10 or 15W amp to the upper parts of the volume knob. I used to play my 15 Ampeg combo against my bandmate's 50 and 100W Marshalls and Mesas. I was on the losing end of that battle, but the Tung Sols helped me cut through a bit better, without having to haul a bunch of **** to the gig.
In my higher headroom amps, however, they have seemed a bit too stiff and sterile. I prefer darker/mushier tubes in high headroom amps.

Re: Tung-Sol 12AX7
On the GC website, they offer the TS 6L6GCs in hard, medium, and soft; which do you use in your HRD? i'm looking to retube my Fender Quad Reverb, and have been considering the mediums.

Re: Tung-Sol 12AX7
I'm pretty sure I got the Mediums. The TS 6l6s are shorter than most other brands, closer to the 5881s, so it your amp has the spring retainer that fits over the top there might not be much tension on the springs

YES. Tungsols in V1 did exactly that in my Tweaker. Clears up things just a bit and helps a lot when pushed in the volume.

Re: Tung-Sol 12AX7
Do the mediums have much clean headroom, or do they break up quickly, would you say?
No, mine has the clips that hold the base. It came with Sovtek tubes, but they're the ones with the "coin" style base, so the clips really don't do much.
