OVERVIEW

Powerful tubes for powerful sounds whether you play blues, jazz, country, or rock.

Built to the same special tube request specs of leading amp manufacturers of the 1960s, Tungsol 6L6 GC STR Power Tubes are rugged and reliable power tubes that excel in the most demanding guitar amp circuits. Choose from soft, medium, or hard in the drop down menu to get the right tube for your needs.

Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal.Soft tubes have lower plate current and transductance matching numbers and reach saturation and break-up quicker. They are perfect for blues guitarists for the because of the tonal break-up and sustain they give you. Hard tubes on the other hand have a much higher amount of clean headroom before they give you that break-up and distortion. With a high plate current and transconductance matching numbers, they take longer to reach full saturation and are the preferred tubes for those into jazz, country, or bass, and guitarists who use various effects pedals for creating distortion. Medium tubes, as you'd think, fall in between these two, as far as break-up, headroom, saturation, etc. and are a more versatile option if you play a little bit of everything.

As a continually touring musician I get the opportunity to try a lot of different tubes. Bottom line is these tubes are made from excellent components and it shows, It's a clear articulate sound. For myself there's not another tube I put this much trust in. Tungsol is the only company I've found not to be cutting corners in production these days. The real point is no tube is going to make your amp better, but these tubes will let you really hear your amp. Nothing less.

I was not able to bias the tubes. The nominal voltage for my amp is 60mv. I could not bias them because the lowest I could bias was 87mv, well out of range. Running the tubes this high will cause them to burn out quickly. I had to returned them:(
I had no problems with the return the people at MF are very easy to work with.

      Comments about Tung-Sol 6L6GC STR Matched Power Tubes:

      Bought these to replace some Ruby 6l6 that came in a new, very expensive, boutique amp. The Rubys were dead sounding, and the RI Tung Sols brought a lot more life to the amp. I'm happy with them. The Tung Sol pair was pretty closely matched and biasing was a breeze.

      These really can't compare to a good set of NOS tubes, but as supplies of those continue to dry up, you have to find something that works. I only have a couple of gigs on these, so time will tell if they will be a good value.

            Tried many 6L6's over the years, from all the big name to NOS tubes... these are a great sounding tube and stand out for all the others in the 6L6 family.
            Clean clear tones, no hiss at idle even with good a amount of gain and when you push them hard either w/amp gain or pedals they break up better than i expected.
            I would gladly buy them again highly recommend them.

                I use this in a Renegade Head and a Fender 100 watt Super Sonic twin combo. I think these sound significantly better than the stock Grove Tubes found in Fenders. These are also very quiet tubes while not playing and reduced high gain hiss.

                  These tubes were well matched within 1mA.
                  The shorter height allowed them to be installed in my Dean Markley signature 60 head where most tubes will not fit. These tubes sound rich and full and break up nicely much better in this amp than the Ruby tubes that were previously installed.

                  I replaced a set of Svetlana's in my Pro-Reverb that had always sounds a bit harsh with no real low-end. These seem to be alot more balanced. I like them and would buy another set in a heartbeat.

                  Comments about Tung-Sol 6L6GC STR Matched Power Tubes:

                  Tung Sol is an old name and in the past, the tubes were better. Nostalgia? Maybe. These work and keep my mind on the music, not trouble shooting. So far...............................Good luck.
                  These tubes feature a small bottle and fit into small enclosures.
                  Time will tell. The sound is really warm and harmonics are good. The tubes are a % of what is needed for good tone. I Biased my amp and used a matched phase inverter. That also makes a difference in a tube amp.
                  Fair price for a quality tube. If you play through a tube amp, you are going to spend $ to make it worth the effort. Otherwise, modeling amps do an acceptable job. Modeling amps sound better than a tube amp that is not properly cared for.

                  These tubes seem to be identical to the Sylvania/Phillips 6L6WGB of the 1980's, a millitary spec'd tube - electrically, mechanically, and sonically. This is an outstanding 6L6 tube. They have the compact bottle of the 5881 but the high plate voltage handling and full 30-35 watt output of the WGB.
