power supply

I've spent the last two months working like mad on a comparison of the new (July 2024) Baby Face Electronics Power Supply, comparing it to my stock recapped SONY PSU and also to the SEASONIC PSU that I've been using since 2018. I also successfully tried the 16AWG wire recommendation by...

Howdy! I’m looking for some advice on fixing a G3 AIO “Molar Mac”. If I disconnect the CRT display cables from the wings card then it’ll boot perfectly fine with an external screen. However if i try to use the internal display then it doesn’t work. On start up there’s no chime, no LED, but...

Hey All, hoping someone can help point me in the right direction. I'm working on a later revision iMac G4 that has a dead power supply. This is one of the later "USB 2.0" 1Ghz revisions and it has a Samsung power supply unit in it with model number: PSCF161101A. The first thing I noticed was...

I just finished re-celling a few iBook G3 battery packs. While this will allow me to use them without being plugged in, and it certainly maximizes the portable nature of these machines, I had a couple thoughts: 1. I do have concerns about the safety of home built packs. I read up on it, bought...

Hey Folks, Just wondering if there is such a thing as a Macintosh Power Supply Compatibility list? Seems like there is some interoperability between certain machines (SE and SE/30 for example) but I haven't seen a comprehensive list of which supplies work with which machines (not yet anyway)...

Hey there, So recently someone asked me to racap a couple macs for him. No problem there but he also asked me to figure out why his one Mac Plus wouldn't turn on properly. As soon as he brought it over it was easy to see the issue, on the back of the unit in clear text was written 220-240V well...

Quick question after a re-cap. Everything seems to be working fine except two oddities. 1. When I replaced the caps, I also replaced the two 220uf 250v capacitors. The kit I got had two very large versions of this capacitor. The values were correct, but they were a little hard to get into that...

Hey folks! A friend of mine saved this Apple 15 inch (Blueberry) display from the recycler and asked if I wanted it. Of course like any sane person I said YES lol Unfortunately this one didn't come with a power supply so I have no way to power it up for testing. I was wondering if one of you...

Online, you can find a lot of discussions related to what power brick to use with Macintosh Portable (the original is M5136 7.5V 1.5A), if it has to be exactly 1.5A or can be more and if it’s worth recapping the power supplies. I decided to at least somehow help in those discussions with...

I spotted a fascinating little gadget in a post to the Vintage Apple Macintosh Enthusiasts Facebook group in April this year. I sent a PM to one of the co-creators, Joakim Larsson , and that led us down the rabbit hole of conversations which resulted in me buying one and then doing the full...

I've been removing it for years but have never put any of it back. Some of it is positioned in a way to it could be for thermal transfer, and some of it has no thermal advantages the way it's located, so it's just there to keep stuff in place/insulated. I'd like to buy some as I have a few...

Greetings all. I recently got a Q700 case with the motherboard and the PSU from a Quadra 650. The caps in the PSU looked really toasted from a hard life with a million hours in at least soft-power-"on". I couldn't find a parts list for the caps in this specific one, so I thought I'd do the...

Hello! I'm new to this forum, so hopefully this is the right place to go :) I recently picked up a Duo Dock for my Powerbook Duo 250. Its got a Magnetek Power Supply (Model 3359-09-001) in it that has failed, and I was hoping I could get some insight. When opening up the power supply to...

Found a listing for a cube and studio CRT ADC and the owner wouldn’t split them apart. I already have a working Cube but always wanted the CRT to go with it. Bit the bullet and bought the bundle, figuring i could sell the cube myself and it’d basically be like I just bought the monitor. Went to...

When taking apart your Apple IIc, you may want to check if the internal power converter has any leaking capacitors. This guide helps you though the process. Note not all power supplies on the IIc are the same. This is meant of the Astec AA7341B, Apple part 699-0230, shown in images below...

I woke up one chilly morning in the middle of December, last year, to an eBay alert. There was a TAM bass unit available for less than $1000! I groggily reviewed the photos and made an impulse purchase after being "awake" for less than 3 minutes. I was in luck but certainly not in a traditional...

I have a bunch of IIci's with power supplies that need recapping. Before I tear one open to put together a list, does anyone have a list of caps needed for IIci power supplies? Even better if it is a DigiKey/Mouser cart...
