Just don't forget to use the tube pinout adapter base!

5751

Pin 1: Plate (Section no. 2)
Pin 2: Grid (Section no. 2)
Pin 3: Cathode (section no. 2)
Pin 4: Heater
Pin 5: Heater
Pin 6: Plate (Section no. 1)
Pin 7: Grid (Section no. 1)
Pin 8: Cathode (Section no. 1)
Pin 9: Heater Center-Tap

**5755

Pin 1 Plate, unit 2
Pin 2 Cathode, unit 2
Pin 3 Grid, unit 2
Pin 4 Heater
Pin 5 Heater
Pin 6 Grid, unit 1
Pin 7 Cathode, unit 1
Pin 8 Plate, unit 1
Pin 9 Heater center-Tap

The only way I would feel safe using the 5755 in place of the 5751 / 12AX7 would be to glue the pinout adapter base to the 5755 tube, LOL.
