Radio alignment is usually noted in the manual for the particular set Sam's , Riders what have you. Generally you are dealing with IF, mixer, oscillator, and rf stages. What you are looking to do is to start with the IF stages. Disable the avc circuit and tune IF adjustment for max output with least signal from the signal generator at the proper IF frequency. Manual will tell you where to connect generator and vom to make readings. Oscillator adjustments will determine where a given station will appear on the radio dial. For non shortwave sets this adjustment can be done by using broadcast stations at each end of the dial. Most inexpensive sets will only have an adjustment for the high end of the band. Here again check the manual. RF stages tune for max output with least signal from generator as per manual.
TV is a different story for another time
