I had replaced the 6L6's in my 68 Twin Reverb back in the 80's. They were ok for while, but then started making nasty hums and crackling. I found they were loosing connection at their base leads (glass to tube leads, not female amp sockets) oxidation - poor construction? So saw someone recommend JJ's. Tried them, half the price, and let say, twice the tone I like. I like them, smooth, even, real sounding, not as loud maybe, but not as harsh either. I can kick the pre-amp and master up a bit more now. Sounds better to me. I got 2 pairs, they had matched pairs. Both came fairly close in match, around 2's. But honestly , all that matching, leave that for the super critical pre-amp buffs for home stereo :)

Ordered these and did receive them fast. One of the 6L6GC's had a huge chunk of the plastic broke off right where it meets the glass. Called in immediately and was told it was "fine" and to just use it...Would have like to had it replaced.

I love these tubes, just NOT this shipment and response from customer service.

        A vast improvement over the stock GT tube.
        Pair it w/ a Tung-Sol 12AX7 and You can't beat it.

          Comments about JJ Electronics 6L6GC Power Vacuum Tube:

          I put the JJ 6L6 matched pair in my Hot Rod Deluxe.
          They sounded even better than the Tung Sol 6L6 pair I have in it.
          The JJ's are creamy, warm and complex
          The Tung Sol 's are a huge improvement over the stock
          Groove tubes.
          The JJ's are heavy in weight
          and feel solid.
          They are a little bit better than the Tung Sol's.

          Right now I run a Tung Sol 12AT7 in position 1 on my Deluxe.
          That's the George Benson modification.
          And a pair of matched Tung Sol 6L6Gc for power tubes.
          My Deluxe is super quiet and has unbelievably beautiful tone
          when I play my Musician's Friend Gibson L5 through it.
          The JJ 12AX7 and 12AT7 sound great too,

              If you do buy these buy them from a company that lets you return them. If you have an amp like the old Fender amps where the tubes are upside down these tubes are narrower than the OEM RCA tubes and the clamps that hold them to not hold them.

                I had to send mine tubes back twice.
                HUGE waste of time.

                  Great Tubes, especially for the price. They get very nice distortion, even at low volumes. However, they seem to be a bit noisy on the clean channel (background hum). But this could be user error, the hum is not noticeable behind any playing.

                                          Needed a new 6l6gc for my vintage PA head guitar amp. The 'vintage NOS' tube I had sourced was microphonic and causing some uncool sounds. Figured I get everything else from MF, so why not? Had it in my hand 2 days later, nicely protected in the box. Put it in the amp and it worked a treat. I am completely satisfied. Made the amp sound way better.
