A 300 mA./12 VDC supply with that trafo is easy. Wire the 2 secondaries in series. Full wave center tap (FWCT) with a MBR20100CT common cathode twin Schottky diode. Filter with a 4700 μF./25 WVDC 'lytic. Follow the filter with a 7812 3 terminal regulator. I would let the heater supply "float". You can always ground the 'X7 heater via a cap. connected to pin 9, if hum or other noise raises its ugly head.
