This actually came in the mail a couple of days ago.
@bluedmc777 sent me lovely vintage NOS tested RCA 12AX7.

I decided to put it in my Friedman IR-D Tube preamp.
I already had a vintage RCA 7025 in V1. The lower gain in V1 gives me a much better clean sound from the Friedman.
And it's a gorgeous clean sound! Anyway, I popped the new RCA 12AX7 in V2 of the Friedman. It's also a bit lower gain than what I had in there.
(Shugang/Ruby 12ax7, which is pretty high gain).
I had to re-jigger my levels to make up for the lower gain but OMG it sounds SO good! Even the with the lower gain tubes, the Friedman still has a tremendous amount of gain. (Think modded JCM800). But with the RCA tubes the gain sounds smoother and more "organic" if that makes sense.
Don had previously sent me a vintage Baldwin branded Raytheon 12Au7, which is now in my SushiBoxFx/C2C Particle Accelerator tube preamp.
I use the Particle Accelerator for my "Fender clean sound" (it's based on the Alembic F2B which in turn is based on a Fender Dual Showman)
Both tube pre's feed into the EFX Loop return of my Frenzel DP525 running a pair of new production Tung Sol 5881's. I use a
Joyo Line Selector to switch between the two pre-amps.
The Friedman IR series are extremely well built preamp pedals and this is my "faux" Friedman Dirty Shirley, actually more like a faux Friedman Twin Sister since the IR-D has 2 channels.

The Particle Accelerator is my favorite circuit from Nathan. Super simple circuit, yet very powerful tone shaping controls and a gorgeous big full Fender clean sound.

And this is my "amp" set up.
