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.

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