Since I've had many questions about recapping, here is my official opinion: Recapping Amiga boards is a must, and not an option. People often ask me to recap faulty boards AFTER it's too late, when the damage is too expensive to repair. Recap in those cases WILL NOT fix problems and additional repair will be needed. So please recap while your board is still working, this is PREVENTIVE. Electrolyte is a translucent liquid, and can't be spotted until it's too late. It can damage IDE ports, tracks, components, audio area. Bottom line: The cost of recap is MUCH lower than the cost of repairs. The endangered species are: A3640 CPU cards, A4000D, A4000T/port modules, A1200, CD32 and A600.
A500 and A2000 A3000 models are better to recap if the machine fails as those caps seldom leak (they usually dry out). All old barrel batteries must be removed ASAP.
Please note that currently I cannot accept repairs due to lack of time (repairs are very unpredictable) I have a full time job and my queue is constantly full with recaps and upgrades. I recommend to get your motherboard refurbished while fully working to avoid repairs altogether. There is very few people who can do GOOD Amiga rework AND accept repairs for the same reason as myself - so best route is PREVENTION.
There are other places that offer recap, BUT what I guarantee is that you get absolutely correct, professional quality, IPC production level soldering work (take a look at my reference pictures below). I've seen many bad recap jobs with burned connectors, pads and components, or just badly soldered. This does not happen with my work. I use professional tools and supplies, and brand capacitors (Panasonic, Nippon Chemicon, Rubycon etc.). I'm probably not the cheapest, but consider this: Say, if you've owned a vintage Ferrari, would you let your brother in-law - who sometimes works on cars - try repair it, or would you take it to a well known and reputable workshop that has extensive experience and the correct tools to make it perfect?
First, declare interest here on the thread, then send me a PM.
Be prepared to disassemble your system and have high resolution photos ready of your board(s) including close-ups of the caps. I only offer the services that are listed, other services are decided on case-by-case basis.

- You must ship the board WELL protected, and ESD safe.
- I follow the queue - first come first serve
- Please understand that this is old hardware and faults could happen ANY TIME.
- I cannot guarantee that I can fix any fault. Many hw. are missing schematics, some logic chip contents are impossible to find etc.
