Editing Sinclair ZX80 Capacitor Replacement Guide (section)

== ZX80 Recapping Procedure ==
# '''Unplug and disassemble''' – Remove the case screws and carefully lift the top shell.  
# '''Remove the PCB''' – Disconnect the keyboard membrane and gently free the main board.
# '''Desolder old capacitors''' – Use a temperature-controlled iron (300–350 °C) and desoldering braid or pump.  
# '''Clean pads''' – Remove old solder and residue; inspect for lifted traces.
# '''Fit new capacitors''' – Match polarity (long lead = +). Axial types fit the original holes; radial types can be bent to fit, but insulate leads with heatshrink or sleeving.
# '''Solder and trim leads''' – Ensure solid joints and no solder bridges.
# '''Clean flux residue''' – Use IPA and a soft brush.
# '''Reassemble and test''' – Power up and confirm stable video and reliable boot.
