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?

@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. 

Swapped out the Sovtek 5AR4 for a Philips 5R4GYS (Thanks Juan !!👍)  

The change was immediately noticeable, so much better all around... ALL AROUND !

More definition across the board, bass notes caught my attention right off.

More edge to the strings, images are wider and deeper. I can definitely hear deeper into the mix.

I`m not a wordsmith by any stretch so I`ll just say that the Philips 5R4GYS is a revelation and is worth every penny.

I`m so very glad I didn`t waste any time trying to get a feel for the Sovtek while breaking it in for 100 + hours.

Had I done so, I would have sat there shaking my head wondering why I didn`t put  the Philips in sooner.

IMO... this ModWright 'T' rectifier power supply upgrade for the ModWright PH 9.0 along with this Philips 5R4GYS tube is quite simply a must have.

I think it`s the best upgrade of a product that I`ve ever done.

Absolutely loving it and should only get better with some hours on it.

 

 

 

@scm I'm glad the tube arrived safely for you and that you are enjoying it. Remember, it was my last one, and a spare, so I wouldn't be surprised if it sounds even better after 100 hours.

The Philips 5R4GYS is a magical tube in any Modwright rectified unit that can take it. In Modwrights, I've used them most recently in my LS-36.5 DM preamp, which I sold off two years ago, along with the SWP 9.0 SE (phono stage I owned prior to PS9.0X) and SWL 9.0 SE preamp (before the LS-36.5 DM). I also used it in the Modwright Transporter, which albeit is over a decade old still sounds equivalent to me than a Lampizator Baltic 3. Dan Wright makes incredible gear for their price points and is one of the priceless people in the audio industry.
