From: Thomas Krueger Subject: Brands of Tubes and Good 12AX7s Date: Mon, 12 Sep 88 7:45:15 CDT It's true, different brands of 12AX7s, or any other tube, for that matter, sound different. Usually the European tubes sound quieter and "faster" than the American counterparts. Different numbers to try in place of the generic 12AX7 include the 6057 (ECC803S) and the 6681. - Tom -- Thomas Krueger, Univ WI Milwaukee, Computing Services, Electronics Shop tjk@csd4.milw.wisc.edu [moderator, info-high-audio] +1 414 229 5172
