    Amazing tubes, massive headroom in my dual rectifier. In my opinion way better than a standard 6l6. Viva tubes are on it thank you. Will purchase again

  • Tung-Sol 7581A Power Tubes

    After reading some reviews online I thought I would give them a try in my PrimaLuna Prologue Premium integrated amp. I have tried several tubes in the past year including Tung-Sol KT150, Siemens RFT EL34, SED Winged C EL34, Gold Lion KT77 reissue and the latest Mullard EL34 reissue. So far my favorite as been the GL KT77's as they have the somewhat sweet midrange of the EL34's but have extended bass and treble plus a huge 3 dimensional soundstage. I've had the 7581A's in the amp for about 8 hours now and I can say with confidence these tubes rival the best I've heard. They have full spectrum sound along with a large soundstage plus great tone like mose of the EL34 types I have heard. I would recommend these tubes for those that want nearly the best out there at a fraction of the cost of ...

  • Very closely matched in circuit, great sound rivaling old blackplates.

    These replaced rca blackplates circa 1960 which were still good. I've only used 2 of these so far, but in circuit I was able to bias them within 0.5ma, which is really closely matched. Immediately it sounded great, but then I cranked up the bias current to a hotter 50ma (up from 35) which this tube is designed to support, and wow! I think I've found my new 6l6 tube type!

  • Great sound tube, like a 6L6 on steroids

    After reading some reviews on this tube, I bought a set to replace the 6550 tubes I was using. To me, these have a more natural sound than the 6550 Sovteks, with a lusher midrange, but still has extended highs and great bass. Should produce less total power than the 6550's , but so far I haven't noticed any real decrease in output. Just make sure your amp can use these, or can be re-biased to use these. Highly recommended.

  • 7581A

    I recently got back into playing guitar after a lengthy hiatus. I've aged a bit and high-gain tube amps are no longer my idea of good tone. Nowadays I'm into volume controlling the amount of grit I play with. I've re-tubed my pre-amp with 5751s and left the Winged =C= 6L6GC that I put in there at least 10+ years ago. While shopping around for tubes online that I really didn't need, (who does that?), I stumbled across some mumblings about Svetlana no longer being the same company that it used to be. They sold out and the Winged =C= tubes are now going for a premium. I figured that I might want to pull those tubes out to set aside and look for a replacement. 1st things 1st: I use a Carvin MTS 3200 head into their open-back 2x12 cabinet. I replaced the stock speakers with Eminence ...

  • The 7581A Beam Pentode Offers An Alternative To Those Looking For A Change!

    Since the Winged =C= factory in St. Petersburg Russia stopped making those glorious almost bulletproof line of power tubes the mainstay replacement for all of our Avian Series amplifiers has always been the Svetlana 6L6GC. It has been a bit of a let-down as to quality and more importantly durability. To be honest though, lately the sound has been fairly close to the originals, especially over the last two to three years. Then a few weeks back along comes one of my customers telling me about this "guitar amplifier" tube that he tried out in his amplifier.... and that I should try it. Apprehensively I started reading about it first.... then I purchased a quad to try out. Since then I have purchased 2 more quads. To tell you the truth... I am pretty excited about this power tube. So ...
