PCB – Universal Two Stage Power Supply v2.0 09/25

New Improved 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.  For a standard power supply schematic showing the position of each component in circuit, take a look at our Universal 60r12SL7 Phono Preamp Power Supply Schematic.

Note these boards are used in our Classic Line Universal 6or12SL7 Phono Preamp (retired), and GU-50 Monoblock Kits.   They have mirror image sides that can be used in either a Left or Right orientation.
