One could think of a [differential] two-stage 2a3 amplifier with overall gain in excess of 100.
Neutralization caps only work cross coupled across a differential stage.
BTW the 7b4 has a mu of 100 but in circuit the stage has a gain of about 55.
In a differential amp, CCS plate loads on the driver tubes would get you a gain of 100 (7b4, 12ax7, etc.) if direct coupled or close to 100 if cap coupled with the largest grid resistors allowed on the output tubes.
