A trick to get 2 volts for the filament is to use two 1.5 volt D-cells in series along with a power supply diode such as the 1N4007. That results in 2.3 volts with fresh batteries which is fine for the radio. Some of these sets have a high/low battery switch to accommodate the range of voltage as the battery weakens. GL, Bill
