Title: 12AX7 and 12AU7 tubes in Stereomour?
Post by: rbc3 on March 19, 2015, 10:59:24 AM

Are 12AX7 and 12AU7 OK to use as drop in replacements of the 12AT7 in a Stereomour with 2A3 output tubes?

Neither of them are equivalent tubes.  They do have the same pin out assignments but they will not be what the design calls for.  Neither will work in the right voltage and current range.
