The Magnavox Electrodynamic speaker has its own power transformer (240 to 24V) and Copper Oxide rectifier to power the electromagnet speaker coil.
Power transformer for radio is mounted in a separate box with Imperia Power Apparatus label on top and connected to the radio by a multi conductor harness.
The turntable motor is a GEC AC synchronous, 220v -240V.
The tone arm is a Split BTH model.
This radiogram has a Raycophone label under the turntable lid marked with Model R7-4. This is possibly due to the fact that this equipment was built during the changeover from Raycophone to Harringtons in April 1930. It was advertised in May, 1930.
