The voltages you measure at the speakers, - Field coil, not Voice Coil (you said VC). Measure relative to GND, on the pin that is not the outermost one - typically this is the pin that is the power supply output to the rest of the sch - to Amp and to the radio tuner.
Actually, measure both pins, inner and outer. This way we will know how much drop there is. The dropout should be around 40+V across the speaker coil that feeds the tuner and around 80V across the speaker coil that feeds the output amp (and a part of the tuner).

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
