Converting Solid State to Tube Rectification on a Preamp

Rodman.... currently on the preamp I have a Schottky Diode 10120a from Cree/Wofspeed.   To me it's the best custom bridge Rectifier that i have try so far.   The Schottky outperformed the Vishay Hexfred ( ultra fast, ultra soft).

A solid state power supply often uses a full-wave-bridge (4 diodes) that can be fed by a power supply winding that does not have a center-tap.

Is it possible to use two 6X5 or one 6X5 with 2 Schottky Diodes, and add a heater transformer to make use of the existing power transformer?

You need to use a center-tapped transformer with a 6x5 to achieve full-wave rectification. 

How about using four rectifier tubes like 6AX4 to create a full-wave bridge?
