For those out there who are collectors of vintage Macintosh computers, you are probably aware of the issues relating to ageing electrolytic capacitors. As electrolytic capacitors get old, they can start leaking corrosive liquid onto the circuit boards. If left untreated, the corrosion can eat through traces, pads and pins of other components, gradually destroying the computer from within.
In order to keep these vintage computers going, it is necessary to replace these old, leaky capacitors with new ones. They can either be replaced with new equivalents (that will also start leaking in a few decades) or they can be replaced with non-leaking tantalum capacitors (my recommendation). It just comes down to whether you want to try and preserve the board as close as possible to its original appearance.
Removal and replacement
If you’re reasonably handy with a soldering iron, this might be a job you’re happy to take on yourself, but it can be a little risky. Sometimes the damage from the old capacitors can be pretty bad, and may require a more expert hand.
I can remove your old capacitors, replace them with new ones, and then give your Mac’s logic board a thorough ultrasonic clean to remove any old residue or dust. And all this for just $80*. Amiga recapping services available too**.
Recapping enquiry form
Australian customers only.
*Basic recapping and clean of Macintosh logic board. Price includes new capacitors. Includes GST. Does not include postage costs. Does not include diagnostics or repair of any additional faults. While all care is taken, no responsibility accepted for any additional faults. Computers in a non-functional state may benefit from capacitor replacement, but it cannot be guaranteed, as the fault may lie elsewhere.
**Due to the higher cost of replacement capacitors, Amiga recapping service is $130.
