Macintosh 128k/512k/Plus 240V Analog Board Recap List

Here is a list of all the capacitors needed for recapping the 630-0108 240v analog board for the Mac 128k, Mac 512k, and Mac Plus. This analog board can run on either 120v or 240v. It will operate on 120v if wire W12 is in place, and in 240v if wire W12 is removed.

These are the highest quality parts currently in stock w/ Mouser. The list is mostly based off JDW's 120v recap video as there is a lot of overlap in parts with the 120v analog board.

Please note that there is no one correct replacement. We are in the middle of a global chip shortage, and the list does not have the most ideal parts as a lot are out of stock and on back order for months. For example, instead of UPW1V222MHD6, choosing UBT1V222MHD would be a higher quality replacement but won't be available for another 6 months. Note that it is available Digi-Key though. I've listed the rating of the original parts above so that you can get an idea of how low of a voltage you can go if and when any of these go out of stock and you need to use a substitute. Please keep in mind diameter and lead spacing when ordering outside this provided list.

Three of the suggested radial capacitors (C5, C10, & C18) are obsolete and no longer produced, so get them while you can.

Attaching images of two boards with original capacitors for reference. Please ping me if you have any suggestions to this list and I will update.

Oh funny I made a similar post at almost the same time. I was considering sharing my Digikey cart, but as you mention availability changes so often. I opted for adding the physical specs instead so someone in the future could find whatever usable options are at the time.

I'll update mine to indicate it's for 630-0102 (the 120V version).
