Yes, you have corrrectly identified secondary (voice coil) winding.
You should see only a few volts, surely not more than 15.
If the tone annoys you disconnect the speaker and put an 4 or 8 ohm 10 watt resistor in it's place. Do not run the set without a speaker or resistor attached to voice coil winding. Remember to re-connect speaker when you are finished.
