Michael. Or maybe you don't need to invent a bicycle.... Make a small transformer power supply unit for 220 volts AC with a step-up transformer and you will have an additional 220 volt network for European radios. Well, I made myself a 110 volt network for American radios. This will solve similar problems for the future.
PS. In addition, pay attention that at a voltage of less than 150 volts, the voltage will be very low not only for the filaments of the radio lamps, but also the anode voltage will drop significantly and the radio will not work well because the sensitivity and output power will drop, and distortions may also appear in the sound amplifier. Make a 220 volt power supply unit, but a transformer one.
