It's tough to review vacuum tubes these days. AND sad to realize that there are precious few good American products out there.

Tung-Sol preamps are the 'go to' tubes of choice here at GREG GUITARS when customers are budget conscious. They perform well and are fairly musical as well. They will not stand up in a head to head competion with average to good NOS RCA tubes, but they will get the job done in all but the "cleanest" applications.

If you're serious about tube technology, our advice is read everything you can get your hands on, then test, test, test. Nothing is a better teacher than personal experience. We use 2 high end tube testers, then load them into a simple lower power amp and play them. You'll soon have your own opinions about Tung-sol and others. Don't simply spend your hard earned cash on Boutique, or NOS antiques. Test!

Start by comparing these with your Fender stock GT's or JJ's, then move onto the GE and RCA, then to Genelex NOS if yu can find them.

However, our own experience tells us that these new Tung-Sols are better than most of what comes stock in a great many production amps. They tend to have an adequate musicality without a piercing high frequency quality. In our experience they are best used in amps that are not involved in recording and amps that are not expected to sound great in a squeaky clean setting.

Bottom line...We use them in a lot of rebuild projects for customers on a budget. We do not get complaints.

I bought eight tubes from MF... out of the four Tung-Sol 12AX7's I ordered, three of the four tested below 40/120, dead-out-of-the-box. Poor, poor, poor quality. When I called to return them, the woman who initially handled the call told me that 'tubes are not returnable if the box has been opened', which is not MF policy. Poor, poor, poor service. It's been seven days since MF confirmed receiving the return, and I still don't have my refund. Poor, poor, poor policy. I bought eight tubes from MF... and only ONE was usable. I also order a matched quartet of Tung-Sol 6L6's... one of the four arrived CRACKED, and the silver coating inside the tube was white, flakey, and burned off. I never used nor even tested this tube, so it was obvious the damage did not occur in shipping, but must have occurred while the set was being tested/matched. Poor, poor, poor.
I will NEVER, repeat NEVER order tubes from Musicians Friend ever again.

      Comments about Tung-Sol 12AX7 Tube:

      Bought this to replace a no name Chinese tube that was noisy, rattled in a 5watt tube amp. Fixed that issue. I am not sure it changed the character of the amp much, certainly nowhere as much as a speaker upgrade.

                      Low harmonics, better gain. Excellent quality overall. I got these as a replacement for the preamp tubes in my Marshall two years ago and I've decided to get the same tubes after I noticed they've aged. If you like clean, high gain, this tube is for you.

                          This tube has poor note definition. I put it in a very high end amp and it's disappointing. Afterwards I read up on tubes and learned that they vary a great deal and the buyer is advised to buy from someone who pre-tests them. Lesson learned. I've already ordered a replacement for this tube.

                                I purchased the Tung Sol 12AX7 to try out in my Hughes & Kettner Cream Machine for comparison with some other preamp tubes and to have as a spare. I am trying out different 12AX7 tubes in the higher gain range based on information I have researched. I rated it 4 stars since I am not certain that I have ever heard a 5 outside of my mind.
                                It lives up to its reputation for low noise along with being rated as one of the higher gain 12AX7s currently on the market. It provides plenty of of tube gain and silky tube compression for a wide range of musical styles across the tonal spectrum.
                                I will be purchasing more Tung Sol 12AX7s for use and as spares in my other tube amps.
