Cap maps — capacitor by capacitor¶
130 boards, 3158 capacitors, location by location: monitor chassis, cabinet power supplies, arcade boards, consoles. A collective community survey by 41 named contributors. Method → Recap.

| Cabinet power supplies | 18 | 215 |
| Arcade game boards | 59 | 1223 |
| Consoles | 31 | 739 |
| Amplifiers, I/O boards, PC and sundry | 16 | 746 |

What these tables are, and what they are not
✅ They are surveys: someone opened a board and wrote down what was on it. ⚠️ They are not a manufacturer specification. A revision changes the list, and no sheet here carries a Sega, Capcom or Nanao part number. ⓘ Read the can before you pull it. Where a sheet and your board disagree, your board is right.
How the values are shown
ⓘ A voltage the sheet does not give shows as —, never as a plausible number. Values are printed in µF, nF or pF by magnitude, without changing them. ⚠️ Sheets that give no locations at all are labelled shopping list: they say what to buy, not where it goes.
⚠️ What did not make it through
ⓘ 114 rows could not be read and are not on these pages: a cell naming no value, a note in place of a figure, a resonator listed among the capacitors. ⚠️ They are counted rather than guessed — the alternative was to publish a plausible number.
ⓘ Five sheets are excluded entirely: three Konami pinouts and a conversion note, which are not cap kits, and one Digi-Key order export whose values live only in Nichicon part numbers — ⚠️ deriving µF and V from a part number would be inventing them.
Credits¶
A collective community effort. 41 contributors are named in the source sheets and credited on each map. ⓘ The origin of the collection as a whole is not established, and this wiki does not invent one.
Review & corrections
How this space is used
Spotted a wrong value, an outdated procedure, a chip reference that does not match your board? Say so here, with what you observed (model, board revision, serial number, measurement). Every report is cross-checked against a source before anything changes — an unverifiable correction is published as “reported by …, not cross-checked” rather than silently applied.
Reading is open to everyone; posting requires signing in with Discord. Reports from the wiki's declared reviewers are handled first; anyone else's are read too, but go through a human before anything is changed.
