03 – Circuit Board Assembly
I chose 1/8″ G-10, a flameproof rated glass epoxy material, for my circuit boards. When purchasing the G-10, I requested the boards to be cut to length (12″ for main circuit board, 4″ for filter cap board) but the main circuit board still needed to be ripped from 3-1/8″ wide to its finish width of …
The original circuit layout had to be redesigned to accommodate the shorter leads of metal film resistors (versus the longer leads of vintage carbon composition resistors). I attempted to maintain the original X-axis component spacing as much as possible, using the original 5F8A layout as a scaled reference. Some modifications were made, such as the …
