6922 tube
"The only real difference between 6922s even of the same manufacture is noise levels."              Just keep typing (eventually, at least one person's bound to agree with that nonsense). 
What's going on with Synergistic Research fuses?
I’m just speculating here, but: back in the days when tubes were a bigger thing, there were quite a few good, major and minor operators, that were contracting others, to turn out and rebrand valves, for them.      Could it be, that Synergistic has... 
... Should I be concerned?
The only possible drawback that I saw, was having two level knobs to adjust.      The simplest, shortest path, is generally the best sounding.        When all the stars are aligned, that is.       KUDOS! 
Whats a good economical way to test the electricity on a circuit?
Not nearly as discerning, but- there’s this type of, "sniffer":         https://www.amazon.com/Digital-Display-Tester-Measuring-Instrument/dp/B082M1BBG3

There are ways to visualize AC line noise, with a newer (FFT feature equipped) O-scope.      The correct Spectrum Analyzer can come in handy, as well.         ie: https://www.testandmeasurementtips.com/measure-powerline-quality-oscilloscope/      ... 
Newproduction power tubes: Reliablity
"Much prefer the Svet new 6550’s, the new plant uses the exact same equipemnt as the burned down plant, NOS Svet 6550 = New Production Svet 6550, exact same tube, "              Wrong!      All New Sensor Corp got from the Svetlana Co was the name... 
Kt88 or 6550 tube for McIntosh MC275
There are no new SED, Winged =C=, Svetlana tubes in production. I really liked them, but- the St Petersburg plant burned down, years ago and SED closed the doors.     Some info from a reputable dealer: https://www.thetubestore.com/winged-c-sed-655... 
Something For The Fuse Guys ...
@  jimkiely-  Personally; I’ve found the tech people and owners at PS Audio very accessible.      You might ask them if they’ve any experience/concerns, with the Synergistic fuses.      https://www.psaudio.com/contact/ 
Newproduction power tubes: Reliablity
The Winged =C= (SED) Svetlana plant made some very reliable power tubes.      I hated to see the company fold, when their plant burned down.     Comparing them to my NOS GE and Sylvania 6550 iterations; their presentation was quite acceptable.    ...

@motzartfan- Should you decide have your tube guy send samples to compare; these pages can offer ideas, far as what to request and sonics to expect:         http://hktubeaudio.homestead.com/files/6dj8.html,                                         ... 
6922 tube
Subjectively, I prefer the cleanest, least colored sound, most 3D staging, most accurate tonality, I can get.     The Germany and Dutch Post shared that preference (back when/probably didn't care about sound stage) and contracted, "specially selec...

Bose makes a clock radio.....oh, wait.....you mentioned, "quality"?     Never mind!

"You'd have to be near deaf not to be able to tell the difference between a NOS 6922 Siemens and Mullard."         FO' SHIZZLE!   
Burn In... the Age Old Question, Cables, Components, and Speakers
Doesn't matter what you call it.     The process will happen, whether you can hear it, believe in it, can figure out how to measure it, like it,  or not. 
... Should I be concerned?
@ insearchofprat - With the Wolze; you can roll 12AU7 tubes and tailor your sound, to your heart’s content.             From what I’ve read about the Morrison; you can enjoy some wonderful transparency.     Two very nice pieces/great potential.  ...
