Really...My favorite power tube is reissue that's not widely popular


If you run 6l6/EL34 variants, I HIGHLY recommend trying this tube out.  The Tung Sol 7581A reissue.  I've had these for a good bit of time and compared them against KT150s, EL34s (several brands), KT88s, and maybe another that I'm forgetting.  They are a mere $30 a pop and they are the best tube I have heard. I know that's a brave bold statement to make as there is so much competition out there and the tube is very much under the radar from what I can tell.  

After having these around for a long time (and in and out of the amp), I had them in and was nearly spellbound one night by how great they sounded upon reentry into my amp.  I did a search and could only find one review, which I agree wholeheartedly with.  You can find it here: https://wallofsound.ca/audioreviews/amplification/6l6-vacuum-tube-review-tubes-courtesy-of-www-thetu...

I am nearly incredulous there isn't hype out there about this tube.  Simply my favorite tube.  I thought I'd pass this along as it may be much cheaper to give them a whirl then fuss with a much more expensive power cord, cable, or other tweak.

Thanks for the review!I'm definitely trying the 7581s.+1 on the Gold Lion tubes.Even their small signal tubes have that golden "house sound".

Just placed my order for a quad of the 7581S Tung Sols.For that price gotta try em:)They’re up against GL KT 88s in an Aric Audio Transcend Push Pull.In other applications I’ve found Tung Sols to be clean,clear but with an annoying glare(like Wolf with his GLs)
Just got the 7581A  tubes today.Very nice.Smooth but lively.Good bass too.This is right out of the box.Very impressive!Thanks jbhiller:)
