Audio Aero Capitole - 6021W subminiature tube ??

So I went in quest for XLR to RCA adapter.
I have found one gold plated which I liked.
But it got PIN3 disconnected and PIN2 connected to center pin of RCA plug.

But looking at my measurement I need one with PIN 2 disconnected and PIN3 connected to center pin of RCA plug.

So appear that XLR wiring is not universal or my Clayton’s quasi-balanced XLR inputs are wired wrong way ?

Or they are two schools of wiring quasi balanced input in power apms?

Usually USA-made equipment uses xlr pin 2 for the positive polarity signal, and pin 3 for the inverted polarity signal. The opposite is done in equipment made in some European and other countries.

Therefore rca-to-xlr adapters that are available in the USA usually connect the rca center pin to pin 2 of the xlr connector.

If the Clayton is indeed designed to use only one of the two differential signals, perhaps it uses pin 3 instead of pin 2 to compensate for a polarity inversion in its internal signal path. Or perhaps its input circuit is somehow defective, or miswired. All I can suggest is trying to contact someone at Clayton, or one of their reps or dealers.

I have just sent inquiry to Clayton. Thanks for advice.

After all hassle appeared that Clayton's have been OK. And AA Cap finally died on me. There is no sound anymore, only quiet hum is coming out of both speakers. So I'm going to take advantage of my misfortune and upgrade it. I'm planning to replace Hovland Musicap with VCap CuTF caps, and Philips Jan 6021W with Sylvania . I have heard that Sylvania's are the best 6021W ? Is it much difference between plain Sylvania's and cryoed Sylvania ? Where can I buy cryoed Sylvania's, I'm having not luck finding them.

About my recent modification:
I have changed Musicaps in my AA Cap to VCap CuTF ($202). After 500 hours of burn in I have started my audition. I hoped that there would be any difference, to my surprise I have got real increase in transparent and resolution. But under the stipulation that AA was powered from AudioMagic Elipse. When powered directly from mains, differences are negligible. Now music is much more involving. Best upgrade I have done recently.
I was so excited about my "reasonably cheap" upgrade success, I decided to upgraded my Jan Philips 6021W stock tubes to cryo Sylvania 6021W.
Another 500 hours of burn in, and I have started my audition, no change in resolution, transparency, but I have lost bass impact and dynamics, I'm really frustrated.

How this could have happened, are not Sylvania's supposed to be better ?
Maybe Sylvania simply do not work well with VCap's ?
Did anybody tried Sylvania's in AA vs Philips ?
What were the results ?
I do not know what to do, pay technician to resoldier my old Philips, or maybe process of soldering tubes charged electrostatically AA board and I have to wait longer for it to discharge ...
