    Follow the tune up procedure exactly as written in the manual. With
familiarity and practice, you'll be able to do it quite quickly. The only
other way for a faster tune up is a  NO tune up radio...get a solid state
rig and you just have to push the power button.
    Zero beating a signal (carrier or CW) should have been covered in your
Basic Qualification class/manual.
    When you hear a carrier or CW signal, you tune the VFO to lower the
pitch until you no longer hear it, just "dead air" or in the case of CW, a
puffing sound. Now you have zero beat the incoming signal. You will find
that the signal you CAN hear will be deviated by about 800 Hz from "zero
beat".
    Zero beating has nothing to do with tuning the final amplifier.
    Analog display also has nothing to do with tuning procedure.
