Best Sounding EL84 - 7189

I have a Scott 299a 2nd. edition, I had it restored a while back, time to update the output tubes.

Wrayray you are correct about the inquiry, it is about tubes. Funny you should mention the GE's and that plant.
I was looking closly at my rectifiers and they are marked
188-5 of course they are GE. You seemed to have left one out of your list, I wouldn't question it; but Amperex it seems is pretty significant with respect to the others.
Any opinion on Amperex?

Thanks for your opinion and all your thoughts, I think I just got lucky. I found a quad of nice used Amperex EL84's
that test real strong. At the same time I came across a quad of NOS RCA 7189's, so I think I will get to hear for myself some of what you are saying.

Wrayray, I ended up with a quad of Amperex 7189 Bugle Boys,
the price was right could not go wrong. In comparison to others I find them smoother and with a more dynamic bottom.

Craig At NOS Valves, great job amp is like new, pumped up the bass and a few other goodies. Craig is very dependable and stands behind his work.
