This guide will help you recap your Apple IIgs power supply, including those nasty smelling safety (RIFA) capacitors.<\/p>\n\n\n\n

Important Note:<\/strong>
A few different companies manufactured power supplies for the Apple IIgs computer. This guide only <\/strong>covers the Dyna Comp<\/strong> model LR62786<\/strong> power supplies. Check the label on the bottom of your power supply to confirm which type you have. Power supplies made by different manufacturers have the same Apple part number, so do not rely on that part number.<\/p>\n\n\n\n

If you don’t want to repair this power supply yourself, I can replace the capacitors on this power supply as part of the repair services<\/strong><\/a> I offer. However, if the transformer is bad, this is something I cannot currently fix. <\/p>\n\n\n\n

Capacitors List:<\/strong>
Please see the table below for a list of capacitors for this model. This information is also included in the high-quality printable PDF version of this guide here<\/strong><\/a>.<\/p>\n\n\n\n

Caution:<\/strong> Part numbers for these capacitors are provided as a courtesy only. Some have suggested that low-ESR capacitors are required for switching power supplies, please keep this in mind when selecting replacement capacitors. Although I have taken care to produce this list, this information is provided strictly AS-IS. You are responsible for doing your own research to confirm that these match the parts you need. I cannot be held responsible for typos or potential damage. This information is subject to change without notice.<\/p>\n\n\n\n

Are you new to recapping?<\/strong> <\/p>\n\n\n\n

If so I highly suggest you watch some tutorial videos and practice, practice, practice<\/em>! on old junk boards, or something you don’t care about (like a broken VCR, etc).

My friend Bruce<\/strong> has some excellent recapping and beginner soldering videos on his YouTube channel<\/a>, as well as suggestions of beginner tools to purchase, check him out!<\/a><\/p>\n\n\n\n
