Although I have more than enough tubes to use in my 4 tube amps, I bought two more pairs through Ebay auction.
I am curious how Amperex ecc83 sound compared with Telefuken ECC83.
Amperex ecc82 is my favorite among 12au7 tubes with nice texture.
Also it will be fun to compare Amperex 6sl7g with Mullard ECC35.
