Tubes don't really have mu either.Pentodes can take on a very wide variety of amplification factors, as can triodes.
A circuit setup for a 12AX7 that has a 12AU7 plugged in will exhibit much lower gain (provided it works at all), and will likely have such piddly grid bias that grid current will be a serious issue.
