In cases like this, the radio's B+ supply can be converted to run on 12v without hurting 'functional originality'. I seldom recommend a BAR (big [censored] resistor) for a 6v radio just because if it's limited current regulating capabilities which causes a harsh 'inrush' of 12v to the radio the moment it's turned on.

Best bet is the standalone power inverter that truckernix suggests.
