Well, I still use the secondary (voice coil) winding and an old analog VTVM to display AC volts resulting from the modulated IF frequency injected into the set as I peak the IF coils from last to first stage in that order. If the noise bothers you, you can sub a 4 ohm resistor for the speaker whilst aligning. My signal generator is a senior citizen too, so I let it warm up for a half hour, and check the output with modern digital frequency counter (which can be had for a pittance.) That way I have an accurate signal to start with, and not much else to muddy the waters.
