  1. I finally finished my video on recapping the SONY CR-44 PSU, which can be used in the SE and SE/30. The video is long but informative. A Mouser Cart is linked in the text description under the video (you'll have to watch it on YouTube to see that), for those of you wanting to easily purchase all the electrolytic capacitors required. You also find a link in that description to my SEASONIC PSU replacement video, for those of you who haven't seen that one either. There's still reason to recap the SONY PSU though -- it's fanless and dead silent when operating. If you have only 1 PDS card and
  2. Has anyone tried replacing the two metal can electrolytic surface mount capacitors on the IIci cache card with tantalum equivalents?
  3. I'm in the planning process to recap the SONY PSU housed inside my Apple HD20SC external hard drive enclosure. (I might make a video.) I've got a Mouser cart filled with mostly Organic Polymer Aluminum Electrolytic capacitors for that PSU (see below), which have very low ESR down to between 12mΩ and 43mΩ. There are many benefits to low ESR capacitors, and the life rating on them is very high compared to regular aluminum electrolytics. But my concern is that the output of some switch-mode (switching) power supplies can ring if the ESR of the output capacitance is too low (as per the data sh
  4. It took me a while but I finally got my SE & SE/30 Analog Board recapping video published to YouTube today. Safari users, note that you'll need Chrome or FireFox to watch it in 4K. Don't forget to watch it on YouTube so you can check out the links I put in the text description (click SHOW MORE to see all of it), including the Mouser Cart that includes all the capacitors you will need. Enjoy.
  5. I made a new walkthrough video about replacing all the electrolytic capacitors on the MicroMac DiiMO 50MHz 68030 accelerator for the SE/30. I explain my choice of Niobium Oxide capacitors over tantalum, show the replacement, then boot and run benchmarks. The SE/30 shown has a recapped motherboard, recapped analog board, and SEASONIC PSU. The video is 4K but if you're a Mac user who loves Safari, you'll need Chrome to view it in 1440p or 4K. Also, it was sadly during the making of this video that my Epic Blunder occurred. My humble thanks to all of you who are so kindly trying to help me in
