In Reply to: low 12AX7 filament voltage in my Fisher X-100-A amp posted by microbe on December 2, 2016 at 22:55:38:
The lower voltage is by design (though it should be 10-11V DC) - the 12AX7's transconductance will be lower, but noise is reduced too.
A matched set of EL84Ms may fix things up with no further action required.
