By the way, a typical tube rectified power supply uses a dual-element rectifier tube and a power transformer with a center-tap secondary wiring. This is a full-wave rectifier. 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. This allows some savings in transformer cost. But both types of power supplies are full-wave. So the issue is not full-wave vs. half-wave.
Converting Solid State to Tube Rectification on a Preamp
I am looking to convert my Preamp from a Bridge Rectifier to a Tube Rectifier. Any members have done or knows how to do this. Your help are much appreciated!

@salectric I might be lost in translations, but full-wave bridge superposes 4x(as signal is phase split by 180deg) half-waves thus pulsation is substantially smoother than to the conventional full-wave method or tube rectification. Literally saying that you’re dealing with 4 superposed half-waves as opposed to 2 superposed half-waves. Pulsation of bridge is nearly 4 times lower in magnitude and closer to the perfect DC. |
If you haven’t already, try some ultrafast/soft recovery HEXFREDs first. Much simpler, and may satisfy your desire for improved sound. ie: (http://www.partsconnexion.com/rectifier_diode_fred.html) &(http://www.partsconnexion.com/rectifier_bridge_hex.html) There’s a blurb on potential benefits, on this page: (https://www.caryaudio.com/upgrades-and-modifications/) |
