I buy my 7581a tubes from Viva also, and only recently noticed the break-in phenomena...I haven't used any actual EL34s since my Had amp can run pretty much anything from 150s to 77s, and I have plenty of those, but yeah...I had recently bought another pair of 7581a tubes for my second Had amp, a Hot Rod version of the version I already own, and liked the sound of my original amp just a little more...until the tubes aged a little, resulting in a pretty much identical sound between the two amps...I'll likely sell one of these amps in the near future so keep your eye out for that in the A'gon tube amp sales area if anyone wants one of these things.
Anyone have experience with the Tung Sol 7581a vs. EL34, KT66, KT88, 6L6
I broke down and added another power tube (Tung Sol 7581a) to my collection. That can get expensive as my Primaluna Dialogue HP Premium integrated has 8 power tubes.
Why has this tube escaped me thus far? Why is it not more popular? Many folks don't sell this reissue tube.
I think this is a great deal. I was torn between the lush, thick midrange of the EL34 and the more evenly spread out sound of the KT88. But the KT88, for all its more correct behavior didn't romance me like an EL34.
The 7581a from Tung Sol can be had cheap and I really like them. [I'll spare you all the audiophile terms]. They check the boxes that I was looking for.
Does anyone have experience, information or knowledge about this splendid tube?
PS The next experiment is KT150s but I can't see doing it if I'm gonna lose any of that great EL34 midrange.
