I had positive results with Schottkys in a PAS filament supply

Posted by 1973shovel on December 28, 2016 at 07:39:49:
I modified a Dynaco PAS years ago (Vorhis Last PAS) and used 1N4007s to replace the selenium rectifier in the filament supply.

After reading so much about Schottky diodes here on the Asylum, and with Eli Duttman calling 1N4007s "bat guano", I decided to try replacing them with two 31DQ10, 3 amp, 100V Schottky diodes.

There was a noticeable improvement in the sound of my preamp, for a total cost of about $1.
