Just a follow up:
I got the T power supply back and I played 3 albums that I`m very familiar with and there's no extra tubey softening or rounding going on at all.
Very clean and detailed.
No added tube noise either which was a concern too. All good !
Not going to leave the Sovtek in there after all so I`ll be looking for a better tube.
@blisshifi ..If you decide you might sell one of those tubes I`m all ears :)
