Modwright PH 9.0X Tube Rolling Question


I recently acquired a used PH 9.0X phono preamp and
I want to upgrade the Russian 6922 tubes. Anyone have
any experience with this particular preamp? I'll be looking
for NOS tubes.

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 :)

Just a pedantic note, 7DJ8 is not equivalent to all those other tubes.  7DJ8 requires a 7V filament supply.  You probably could get away with an actual 6.3V, since most tubes allow a 10% error, but no less than 6.3V for best results.

Since the T  power supply isn't adding any "tubeyness".....what does it do better than the SS power supply?

@lula It` doesn`t add too much tube sound is what I meant.
It sounds great and it`s way far from being broke in.
 I`m certain it will get better with more time on it.

 

@scm I forgot to look into this for you, but I probably have something. Let me PM you and follow up with you tmw.
