No, because the 12 Volt radio's circuitry is set up to give the correct biases to the transistors when you put in 12 (actually 14) volts. Tube sets won't work because the tube filaments won't even be visibly warm at 1/2 voltage. The Early Blaupunkt sets were set up to be convertable from 12 to 6 V, positive or negative ground. They did this by building them as 6V sets and setting them up so two halves could be connected in series for 12 V or parallel for 6V operation.
