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.  


I agree that tube rectification adds a certain je ne c’est quoi, but I have never understood why.  Among solid state rectifiers, only Schottkly diodes equal or surpass tube rectifiers in my personal experience. (Others may legitimately differ.) Does Wright use a choke load on the rectifier tube?
