RE: [Harp-L] 12au7 tubes

 Try them all and let your ear determine that.  Some component values drift and may sound different in one Bassman to the next or any amp for that matter.steve--- On Wed 06/21, JAMES SUPRA < suprajames66@xxxxxxxxxxx > wrote:From: JAMES SUPRA [mailto: suprajames66@xxxxxxxxxxx]To: harp-l@xxxxxxxxxxxxxx: Wed, 21 Jun 2006 20:15:06 -0400Subject: [Harp-L] 12au7 tubesIf im stand behind my Baseman, looking at the back of it. Will it make a difference what pre amp (12ax7) i replace with one 12au7? Meaning , should i put the au7 in the 1st , 2nd or 3rd? or doesn't it make a difference? I want to start by only changing one pre amp tube.Thank you in advance for anyone's feedback.James Supra_________________________________________________________________Is your PC infected?
