    6-0-6 means 12v center tapped. 6v CT would be written 3-0-3.

    Well, either let the transformer protect itself or add a small fuse in series with its primary. Under 1/4A fuses get real expensive. ANd a charging cap could offer a nuisance blow on a truly tiny fuse anyway.

    If it is 6v on each half, I don;t know what the advantage would be of using half of it. Use both sides and go full wave. Doubling half instead of using the whole winding seems pointless. If it is 12v across, then use that. If it is 6v across, that rectifies and filters to about 8-9 volts DC.
