Mnats designed the Rev F PCB in order to utilize Ed Anderson’s clone of the Bournes B11148 output transformer used in the original 1176LN revision F compressors.  The result is an authentic replica of the revision F circuit including the transformers, transistors, T-attenuator, and component values.
