Tungsram 12AX7/ECC83- When I think of this tube, I think of turning up the color much in the same way the classic Mullards do... smooth, maintains top end, excellent bass. The midrange especially is fabulous. We had just run out of this tube not to long ago, and it was looking grim for all our customers who are big fans of them... but happy days are here again! I just found a nice whack of them, all grades available!
