PCB – Universal Single Stage Power Supply v2.0 09/21

High Quality PCB, 2 layers (top & bottom), heavy 2.0mm fiberglass board (FR4-Standard Tg  130-140c), 73 x 90mm (2 7/8″ x 3 9/16″), surface finish HASL (lead) pads, heavy 2.0 oz. copper traces.  Can be used for a full bridge (no centre tap on power transformer = 4 diodes) or as a full wave (centre tap on power transformer = 2 diodes).  If using the 2 diode configuration use D1 & D2 only.  Here is a link to our Yuri Kit Monoblock Power Supply Schematic that uses this board (note R2 is a safety bleeder, i’d recommend 470k 2w).

Note these boards are used in our Universal 6or12SN7 Preamp, and Yuri Mono Block kits.  They have mirror image sides that can be used in either a Left or Right orientation.
