Capacitor maps
Where every electrolytic capacitor sits on Amiga and ZX Spectrum boards, with its value, voltage and type. To take to the workbench, or to know what to order before a recap.
A recap needs a temperature-controlled soldering iron and SMD experience. Capacitors that have leaked leave electrolyte that eats the traces: it must be cleaned before the new ones go in. If you have never done it, bring us the board.
