Sure you can, but she will probably borrow some of your 6sn7 tubes to see which ones make the most difference. Maybe a tungsol bgrp, I heard they help tighten the bottom end....

The one with the grey glass?  It has better resolution than the black glass NU but I didn't care for the tone.  Imagine the RCA grey glass only shouty and edgy in  the upper mid lower treble range instead of lush.  May have just been that tube, it was noisy so maybe it wasn't run enough to be broken in.

Yep, that's the one.  They are rather rare, the black glass is far more common.  I'm not sure my impressions are all that valid given the circumstances of the listening session, but FWIW I didn't care for them.  I know some people pursue these particular tubes pretty aggressively though.

Any of you guys can describe the sound of the National Union NAVY 6sn7gt?  I am talking about the long one.  Any info?

Can I borrow it when you are finished to tone mine please?
Promise I'll be very careful with it.
No need to send it with a tube I'll use one of my own.
 
As for the Grey Glass NU they are very nice tubes.
I tried them with my SP and they sounded great.
Never tried them with my Glenn OTL yet.

The Tung Sol have different supports at the top mica.
 
They look like Sylvania to me too.
