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.

      Replaced the stock Chinese tubes in my Vox AC10c1 with Tungsol and now the amp sounds clearer, with more defined bass and crisper string definition. Love it!

        Comments about Tung-Sol 12AX7 Tube:

        Put this in an Orange micro dark, and immediately noticed the difference from the stock tube. Gave an already feisty little amp some more growl. Definitely worth the money, and an easy swap for a marked difference in tone.

            Comments about Tung-Sol 12AX7 Tube:

            These are clear, and articulate. 4 for 4, and I'm ordering more now. I ran them on a Bivalve and BFPR against 2 other russians and 6 or 8 oldies. No micro, no midchord hash or extra bass burnout. Not as good as the best of my old stuff, but I give them a nine (and you can buy more).

                    Looks like a well made 12ax7. I tried it in position V1 in a Bogner Shiva, 6L6 version. I found it to be bright sounding with that amp. I went back to my original tube. It was quiet during operation.

                        Replaced some failing Ruby 12ax7s with these. Sounds good in the amp in the V1 position in a Bassman clone. Time will tell if they hold up. I haven't had a lot of luck with any currently manufactured pre amp tubes, but my stash of NOS tubes is about gone, so I'm hoping that these will do the job.

                          Fairly quiet, functional 12AX7s - even on the ridiculous gain levels of the old Hot Rod Deluxes on the red channel.

                          Lets the typical chime and Fender 6L6 tone come out well - bright, but balanced. As good as any new production tube I've yet used, and as good as some of the old ones in my stash in terms of overall sound.

                          Will see how they last - been running a set of Tung Sol 6L6s for over a year pretty hard (including attenuator), and they're still sounding as good as when I put 'em in. I'd assume these should have acceptable longevity as well.

                          They haven't gotten splatty with very, very high input levels either - I hit the front end of the amp with an old Space Echo and it's a VERY hot signal.

                                  I recently bought a 86 model Marshall 2205. The guy had put in JJs all across the board, I made that mistake too. JJs are a good tube but not inevery position. When I inserted the Tung Sol in V1...WOW!!! It almost sounded like an entirely different amp. It sounds more focused and more aggresive. I love it for 80's metal in V1. Left the JJ in V2 for cleans. This is my third Tung Sol and havent come across a bad one yet, highly recommend for rock.
