Rewiring the 4 -12VDC filament phono amp and tone control 12AX7's would be a first class pain in the ass as this would also require you to tweak the total layout of the fixed bias circuit to make sure power tube bias isn't affected as well...and forget about tube rolling after you make that change. Why bother when the Sovtek 12AX7LPS is such a nice sounding, quiet tube? I've also had good luck with the recent JJ's too. None of these are all that expensive either.MAK
