I am building an amplifier based on instructions found in “A Complete Guide to Design and Build A Hi-Fi LM3886 Amplifier.” I am designing my own PCB, since I have not found a commercial one that will fit my existing heatsink and chassis. The design calls for a 4.7 µF input coupling capacitor. I am debating between using a quality electrolytic (Nichicon UFW) or a film type (MultiCap) mounted vertically – horizontal mounting is not a option due to board size constraints. The film type is probably preferred, but I am concerned about the vertical mounting. Any thoughts or advice would be appreciated.
