Need matched power tubes? Don't worry! Price includes matching in any quantity you need for no extra charge. Need a matched pair? Just order "2" tubes. For a matched quad order "4" tubes. Matched sextets and octets are available as well.

You need more clean headroom?  The new Tung-Sol 7581A vacuum tube is the answer.  This tube is an upgraded 6L6GC tube but willprovide more headroom than typical 6L6GC tubes. The 7581-A power tube has a plate dissipation rating of 35W, as opposed to the 6L6GC and 7581 rating of 30W.  The 7581A tube can be used in any 6L6 based tube circuit.

From our review: "Balanced, is the first word that comes to mind when I think about the sound. Other descriptive words would include detailed, rich and responsive. The bass response, midrange and treble were very balanced and the EQ could essentially be left flat.Very rich sounding with enough shimmer and harmonics to put a smile on my face."

A fantastic choice for your Fender tube amp, Ampeg amps normally using 7027A tubes, Music Man amps, or any other 6L6 based tube amp where you need to increase headroom.

I just installed these tubes in a fresh Super Reverb Clone build. This amp features Mercury Magnetics,combination of double shielded PIO/Polypropelene capacitors, carbon comp resistors, and a modified tone stack that works every time. Before I installed these tubes I had 6L6GC-STR's. They actually sounded superb. I really didn't expect what this tube will do. Strong Clean Head Room with power. Reminds me of that 6L6 Winged C tube they quit making a few years back. Well balanced tone. If you like clean and strong, I can't imagine you would be disappointed.

An Amazing Tube

by

I had a few friends test one of these in a little SE amp. It has been listened to by a few really good players and the response has been amazing. I sent out a kit with a NOS Sylvania 6L6GC, a Tung Sol 6L6GC-STR, and this Tungsol 7581A tube. I told the boys to swap them out and tell me what they thought was best. Everyone thought the 7581A was way better. A buddy of mine did the test using his favourite tube, the 6L6WGB that was made by Philips/Sylvania. Even that tube came in second and it’s an amazing tube.
