Modwright PH 9.0X Tube Rolling Question

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.

@scm

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.
