12AX7 Tung-Sol twin triode.

Tung-Sol Claim the following  ""The Ultimate 12AX7. Big, warm, and musical. High Gain, ultra-low microphonics, and superb linearity with a dynamic 3-D sound.""

What I will say is that these tubes are without a doubt a high-quality preamp tube recognised as one of the best on the market.

The Tung-Sol 12AX7 ECC83 (sometimes call a 12AX7 and sometimes called an ECC83.. (both are accurate) is a twin triode running on 12.6V and 150mA in series or 6.3V @300mA parallel. Essentially this tube is two independent High-MU triodes utilising a 9 pin base (see any of our B9A range of sockets for the right base).

This tube works great for amplifying your sound but also works well as a phase inverter tube or in vibrato circuits.

 A PDF has been attached,  to show the tube specifications including the height and width of the tube.

Question: So do I use these? 

Well, to be honest, I have to try and use all tubes to really get a handle on what works. That's my excuse for having so many amps, however, the short answer is yes. I definitely do. I find these tubes to work well in pretty well every amp I use but I do appreciate different tones. Often forums and blogs that have strong opinions are based on a preference for a tone although there are some tubes that appear to suit some amps better.  If you want a definite answer then you probably need to consider the following.

1. What is your amp?

2. What style of music do you like to play?

3. What guitar do you use to play through this amp?

4. Look for people who have the same amp and like the same sort of music and ask them if they know any secrets

All these things have a factor in the sound.. as does the age of the caps, transformers, speakers etc. Just experiment or read a forum that doesn't know any of these things but has a strong opinion on the subject. perhaps they know something you dont..

Finally: Have you tried a tube roll pack.. 6 of the best preamp tubes around and you can experiment with tones.. once you find the sound you like then sell the remainders to a friend or on ebay ;)

What is the ideal use for this tube?

The 12AX7 is a 9 pin tube commonly found in the preamp stage of guitar amps. 
It is also highly recommended for studio pre-amps and hi-fi gear.

Great bang for the buck.. a good all-around performer without paying too much.
