Description
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.
Universal style board with jumpers and options for different circuit topologies. Designed to be used with dual triode loktal tubes such as the 7N7, 7F7, 7AF7, 14N7, 14F7, 14AF7. Where one section is used for voltage amplifying, and the second section is used as a cathode follower/driver stage.
There is no schematic available for these PCB’s, but they are fairly easy to trace and figure out.
