RE: In what spirit do you ask the question ??..

No problem. I over-reacted, because I get tired of some people's posting, and likely vice-versa about me !!

None of these tube devices are perfect. We have to do and use whatever we can, the best compromise, and design with them !!!

I see you use 45s. I could not get that tube to go well in 2015 -2016. In the middle midrange, I always hear a broad but shallow suck out, despite it doing other lovely things that would catch people's attention. Very noticeable on well-recorded solo piano.

Dennis Fraker, heard the same Type 45 traits in his place in Montana. Listen to a JJ 2A3-40 in your amp, don't really have to change the 5K output trannie, just the Rk, and not even that on a first-try basis. It ATE my ST 45s.

I am selling all my 45s, sixty eight of them, on eBay. I start with 47 of the TV-7 passable tubes, tonight, 30 auctions, spaced apart every seven minutes. I have a dozen JJ 2A3-40s now at home, enough for me, two times over. Just pop in some JJs and compare them, see if you can borrow two, using 45 biasing even !!
