I'm building a power supply for an 8 transistor radio, that originally used 6 "D" cells, involving a rectifier bridge, filtering caps etc, but there's on problem,which is I can't seem to find an AC transformer outputting 6 volts that fits in the case I want to use. I have no problem using a wall wart, but I can't find one of the correct voltage. I have one rated at 9 VAC, outputting in the range of12.5-13 VAC. Is there a way to halve this voltage with resistors without generating too much heat?
