Recap guide
Recap the Commodore Amiga 1000
The A1000 supply is the usual cap target, and board revisions mix old and new parts.

Worth a recap. Reports say it is a common and useful fix on this machine.
Where to start
Clues from write-ups and forum threads, not a diagnosis. Low confidence means one thread or one repair; high means several write-ups agree.
- Power supply electrolytics (Medium confidence). One restoration log replaced all the caps and found one replacement too tall to fit. A service listing says it replaces all PSU input and output electrolytics. Source
Tips, tales and maybes
Found in write-ups and forum threads. These are other people's reports, not tested by us. Check part references and values against your own board.
- Tip: ESR test before swapping the big HV cap (Medium confidence). An A1000 restoration kept the original high-voltage cap after an ESR test showed it excellent, since the new part was too tall for the case. Commenters suggested checking C42 on the high-voltage side, which they thought was an X2 cap rather than a Rifa. Source
Before you start
- Boards changed during production. Check your board number against the guides before you order parts.

Steps, tools and safety
The steps, the tools in top, middle and budget picks, and the safety list are the same for every machine, so they live on one page: How to recap, step by step.
Values are shown as published in the guides above, and boards changed during production. Check the board in front of you. A recap involves hot tools and, on some machines, dangerous voltages. You do it at your own risk.
