First question in my SP9 pre is it important to use all 4 12ax7 that are balanced witch 2 slots are inventors the ones to the front or rear...
in my st 120 is it more important to have a balanced tube in the center...any info would be appreciated..
i do have a variety of ax7 au7 that are balanced and many that are un balanced by as much as 4 points as tested on an orange tube tester this link should show what i am working with Bob B
