Consider using a LT0183 regulator. You can get two samples free from
Linear Technologies. It's good for 7.5 amps and will not need much of
a heat sink. A few resistors and caps are required to set the voltage
up to 12 volts.
Another way is via a string of series diodes.

I use a plug-in power brink from an old notebook computer. I think mine
outputs 15V and then this gets dropped to 12V and 5V with a RC filter and
regulators.

I'm using an HP 37203A case (half size) for my GPSDO project, but the
output from the transformer is just too high to get +12V @ 1A to power the
OCXO from a simple regulator. So, what are people using for quick and
dirty 12V 1+A power supplies? I'm not in love with the idea of using a
wall wart, but I could look the other way. Does anyone know of a small,
cheap, quiet switching module I could use for this?
