RE: RCA RED BASE 5692

If your friend has them, one of the most sought after 6SN7s are the Tung Sol Round Plates , which are in black glass bottles. People love them for all sorts of reasons, I suggest you ask for those.
I used to roll tubes like you want to now with your 12AU7s to 12AT7s. Bear in mind that there is more than just gain differences and it may not be in your phono stage's best interest to make that switch. If the manufacturer say it is OK then by all means. but I would ask around and see if anyone else has done that. The pin out, will likely tolerate it but it is hard to know if it stresses the amp in some way, just saying. I don't know why I have become this conservative, I used to try any tube that would work even if just a little bit. I am using a one tube headphone amp which came with a 12AU7 (Shuguang) which I rolled with an Amperex 7316. Your courage with the 12AU7 to AT7 has me thinking.....
