Electrolytic capacitor kit: enough to recap an entire board

On machines from the 80s and 90s, capacitors dry out, swell, then leak and eat away at the traces. The fault shows up as crackling sound, a shaky picture or a console that no longer starts. This kit brings together through-hole radial capacitors from 0.1 to 1000 µF, at 16, 25 and 50 V, all rated for 105 °C: so you have the right value to hand when it's time to recap, without reordering part by part.

What it does

• A wide range of values: from 0.1 µF to 1000 µF, spread across 10, 15 or 24 values depending on the pack chosen.
• Three rated voltages: 16 V, 25 V and 50 V, the three you come across most often on a console or arcade board.
• 105 °C models: more durable than the original 85 °C parts, useful near a regulator or heatsink.
• Assortment sorted by value: take what you need and keep the rest for the next project.

What it doesn't do

• These are capacitors with through-hole leads, not surface-mount components: they are not suitable for all-SMD boards, where the capacitors are soldered flat.
• This is not a kit dedicated to a specific console. There is no guarantee that all the values for a given board are included, or in sufficient quantity: make your list before ordering.
• No voltage above 50 V: mains power supply units and high-voltage switching stages are not covered.
• The kit does not replace tantalum, ceramic or film capacitors.
• No soldering iron, braid or desoldering pump: tools are not included.

Compatibility

Any through-hole circuit board whose values are in the assortment: 8-bit and 16-bit consoles and microcomputers, arcade boards, linear power supplies, vintage amps and monitors. What is not covered: fully surface-mount boards (handheld consoles and machines from later generations), and any value or voltage not in the assortment. Check the markings on your original capacitors — capacitance in µF and voltage in V — before ordering.

Skill level required

Soldering required, intermediate level. You need to desolder each original capacitor without lifting a pad, then solder in the new one observing polarity: the light stripe on the body marks the negative lead. Have a temperature-controlled iron, braid or a desoldering pump, isopropyl alcohol to clean off flux and a multimeter to check afterwards. Identical capacitance and a voltage equal to or higher than the original: never the other way round.
