If this refers to the Brimar VA11 amplifier on your ECC807 thread, then you could simply use the two diodes and centre tap to 0 volts idea (that is a 'full wave' rectifier). The current available will be what ever the transformer is rated at. Yes you will get 400+ volts DC, but that is what is needed?

For information, if you did parallel the two 300 volt windings do not assume you would get 2 x the current. Unless the transformer is rated for use in bridge mode best to estimate 2/3 the 'total' current.
