[Labs] Replace your Apple II Power Supply!
HTML-код
- Опубликовано: 27 окт 2024
- Today on Macintosh Librarian Labs, Ms. Fox installs and reviews the Universal PSU Kit from ReactiveMicro for her Apple IIE computer.
This all started with magic smoke coming out of the blown RIFA capacitor in the Apple IIE.
Rather than just replacing the RIFA capacitor, the new Universal PSU kit give the Apple II a more efficient, modern power supply that will surely last several more decades.
Also, she pulls our her thermal camera to find out just how cool the new power supply really is!
This is not a sponsored video. I am just a nerd who wanted to talk about a new power supply :P
Also, stay tuned to the end for a Macintosh Librarian Mini featuring Maccy and Towee the Apple IIE!

Great video! Appreciate that you kept in the finicky connector bits.
"Macintosh Shenanegans" I think Sean copyrighted that!
I truly love your videos (and being so pleasant to watch, is a big plus 😍). Back around 1985 (yep, I'm not a young guy) I had to do something very similar to my Atari 1040ST. Unfortunately, there was no room inside the unit to install the higher-powered replacement I purchased from Jameco, so I created a metal enclosure and placed it outside unit. It is in my garage now for more than 25-years, and I plan on making a video about trying to use it again 😊
Great video. I love a good RIFA cap explosion. I had one explode in a Macintosh II power supply, and it scared the crap out of me. Lucky I got it on video - 3 different camera angles.
Thank goodness places like Reactive Micro exist. I’ve purchased a few things from them to make working with my //gs and vintage Mac collection a whole lot easier. 😉👍
Sometimes the algorithm knows exactly what I need.
I like when you do unscripted videos and shoot from the hip. As for the original IIe power supply, I had no idea they ran that hot! I'll need to check mine. I've recapped my entire power supply, however the Reactive Micro power supplies are really nice and I have one on hand for if/when I do the upgrade like you.
Thank you Sean! I know you have told me that I need to do more unscripted stuff! I think i am found a good workflow for them :)
That "Return of the MAC" at the end, pure dopeness!
Hey this is super handy! I have a IIe in the garage that I picked up last summer, hasn't been turned on in 20 years and very likely needs various new caps and I've been putting off fixing it. With this and your other IIe videos I'm inspired to get it running again!
Well done, Ms. Fox! As someone who recently had a Apple power supply explode, this was quite the education!
It’s a great investment !
Mine is about to explode, thank god I ordered a replacement a week ago! Runs super hot and the RIFA filter cap is extremely cracked. Just got this Apple II for free WITH a huge box of games, but already about to blow after one use. :(
I was working in Kalamazoo michagan three years ago. I remember the computer show and saw old pcs. I was inspired which i found my newton and got it to work. Thanks for your video. I had Macintosh 1989. Great memories. I build my first IBm clone 1985 I purchased all my parts from micro center in Tustin which is still standing. I remember compusa newegg and other companies great memories. Today, I try to stay away from tech but this is a hobby.. I surf more. HB pier Downey California ❤❤❤
And I was worried that Maccy was not going to say a thing in this one. Great video. In Canada, "Les Mains" means hands in French.
That’s a nice modern solution to the RIFA issue. Nice job, also the studio is looking great!
it is an awful solution, those PSU's dont last.
I discovered your channels via Action Retro. Very good content and production! I hope you get some more subscribers.
That IIc LCD in the background makes me so jealous.
Just a thought, but the IIe power supply was probably running hotter than usual since the extra metal cover may have been acting as another heat sink maybe. I personally just replace the rifa caps everytime I get another apple IIplus or IIe since it’s only a matter of when it will explode/melt. 5-10 buck fix. :)
I don’t own any old Apple devices but I do enjoyed watching this video. Pleasure to watch and listen.
Not an apple guy, but found the replacement pretty interesting. Thanks for the video.
I repair vintage audio gear, and a lot of high-end gear from years ago (Studer/Revox, I'm looking at you here) used Rifa caps. Those caps are on my "replace on sight" list. I replace them even if they're perfectly fine when I find them. They're also used as snubber caps on the power switches of Dual turntables.
Even though I do not own a IIe, I have tinkered occasionally with electronics, and I feel like I learned some important to-know things about working with power supplies.
Thank you I just purchased a power supply from them
That's a merch idea right there.
Maccy on a sticker that says "Warning. Do not open this. You might die."
After working on compact Macs and early iMacs, it's nice to not have to worry about the CRT. Still gotta watch those high-voltage caps though 👍
Great video, bringing back the memories. Trying hard to recall if we had Apple II or IIe at high school in the late 80s...🤔I think they were IIe. I do know on cold winter days in New England those computers were good hand warmers. What I remember most was my older brother gave me his class disk he had been storing for years with games on it to play during class. Never got caught.
Good video, it's good to see you all back making videos.
Very nice! Yep, seems like in the end it would've been easier to just solder the mains wires than to use those connectors, though is an option for those who do not have the ability to do so. I really like the low voltage wire loom it comes with, handy!
Very helpful video. That thermal imager is awesome btw!
A new power supply is really the easy way out, but replacing the caps in the old power supply would pretty well bring it right back up to scratch and would work exactly how intended. The modern power supply may seem to be a nice way to protect your equipment, but in reality, the modern power supply could actually cause my trouble than it is worth. With these old machines, they re designed to run on the older style, often at least partly linear power supplies. Depends how technical you are.
New power supply is a great idea for those who don;t know how to properly rebuild the old one, but be aware of the possibility of more interference on the DC lines and possible longer term issues with the equipment not designed to use them.
I don’t even like Macs but you’re adorable with a great presenting and editing style.
Loving the 80s soundtrack as the perfect complement to this retro tech!
This must be the most adorable electronics repair video ever. Wallace and Grommit. Mull-Tim-Iter... love it...
The cutest Macintosh channel of RUclips. I am on the PC side, but love your videos.
Nice walkthrough!
Thank you 👍 I love your channel!
@@MacintoshLibrarian JDW's channel is wonderful! So much good information!
New fan here... Great Channel! i have been using Apple computers since 1977 and owned so many over my life. Made my entire career as a graphic designer wIth them. Apple IIe. MacPlus, Mac IIFX, Quadra, Power ComputIng Power Tower Pro, Cube and so on. The fIrst art I created back In '77 was generated by hand codIng each poInt on an XY grId In basIc. Compared to today where we can ask AI to draw whatever we want In 5 seconds. Love your channel, and you are so cute ; )
Awesome Ms. Fox! I just did this last week for my IIGS! What a great kit. Also, Macy over your shoulder is making me laugh.
Yay! Thank you! I have a second kit that I am planning on installing on my IIgs
@@MacintoshLibrarian one quick note - I did end up soldering the mains with my IIgs power supply. The gage between the wires was making it seem less secure that I wanted.
@@ericmbusa Soldering it is a good idea :) It is definitely more secure. I just want to spread the word about these Wago connectors :P
this was a great simple upgrade to keep the IIE going for years to come, also ad that this girl is extremely cute and pretty 😊
I like these Labs Vids, Kate! Give us more LOL
Super cool I did that PSU last year i have my Apple IIe all setup i just need a mouse.
but projects right now are Finishing my Commodore 1581 FDD :D
This is the 2nd time in a week I heard about those wago connectors(and never heard about them before!)
For my apple 3 I ended up using wire nuts, but I'll probably end up popping the PSU out again and solder it. The reactive micro PSUs are really awesome and I want to pick up more for my Apple IIs
WAGO! WAGO! WAGO! I use them in my walls !
@@MacintoshLibrarian And it's fun to say!
Wagos are fantastic. Our house suffered a lightning strike that took out about half of my “smart” Z-Wave switches (crispy burnt). As I’m restoring these switches that are already beefy in size and hard to stuff into the electrical boxes, I decided to reorganize one of the messier boxes (three dead switches) I used wagos to replace twist nuts. What a difference! If you take time to manage the wires you can gain extra space in the wall box which is good not only because it’s easier to work in the box but also allows more cooling.
WoW Kate Very nice upgrade that Is really the way to go on thoses Apple ll Power Supply Oh its Always nice to see Maccy and Towee very cool
Great video! Your scripted videos are great and your unscripted ones even better!
Or was this scripted and your getting so good at making it look unscripted?
Yikes! Didn’t realize there was a Rifa in my apple ][ psu. Great video, especially the comparison using the thermal camera. Those old power transistors get pretty hot. Combine that with the aging PCB coating and the result is a lovely diffuser of essential 80’s electronics 😂
I'm not a Mac guy, but I'm subscribing. 😊
What a coincidence, I just bought a really interesting looking Apple II clone which has no power supply. Presumably it was removed because it blew up, since I'm guessing it wasn't made as well as the original Apple one.
I looked at the RM store (might want to double-check your link in the description, I got a page not found error), and unfortunately their price for shipping to Australia was almost as much as the kit itself. And since I don't have the power supply enclosure, I'd probably need the full replacement PSU, rather than just the kit, which would cost even more to ship. But that's fine, I can build my own solution anyway.
I'm still waiting for the machine to arrive from the electronic bay. It has a full keyboard and numpad like the Platinum, and capslock key so I'm hoping that means it does lowercase like the IIe. Oddly it has no Apple keys like the original II or II Plus, but it has 64K of memory, so I'm not really sure what it is.
Thank you! i fixed the link ! That sounds like a very unique clone!
Look me up on face book in the Apple II enthusiast group, I can put you in touch with somebody in Australia that will sell you an old refurbished PSU that will last.
Great timing with KansasFest this week!
Been debating on taking the air compressor to my PC but the static might fry it when I turn it back on. YOLO?
Funny: just before you used the Wago connector, I was wondering, "would it be okay to use a Wago inline connector there?" It's a great option for mating incongruent ends, isn't it?
Huzzah! Thank you Ms Fox for another great video 🙂 I think the power supply in my 1998 iMac might need a refurb soon. Any suggestions?
Great video! I didn't know you were so hardware electronics literate. I'm jelly.
Yes! I am secretly an electrical engineer :)
@@MacintoshLibrarian With that smiley, I'm not sure if you are actually an electrical engineer (only since that would make sense) or just making a joke (as it would imply).
19:58, no, squeeze connectors are never fine. They always perform precisely as they performed here. You can put 9000 lbs of clamp pressure on them and the wires still slide right out. It's a miracle.
I've used them several times for automotive/trailer connections, but never on a car I wanted to keep. They always seem to cause just as many connection problems as they solve.
21:30 Ha! I keep calling it "Action Replay" instead of "Total Replay" too. :D
Nice.. one of the few people online pairing their Apple //e with an A2M2010 monitor, which is the correct thing to do.
Why take the old PSU board out of it's can? We can just mount the new PSU in place with it's own connectors and nothing else. It's recommended to run the PSU without a cover on, inside the machine, as long as it's properly seated, for better cooling. I run the G4 cube out of it's chassis most of the time, to keep it cooler. It's running a Sonnet afterall, as for the soldering, the contacts better be tight, otherwise they will heat up just like the old power supply does. Btw, that old power supply heats up so bad due to everything turning into a resistive load in it. Including the transistor. Every component, even the board, lose their conductive properties and start to dissipate heat. My 1989 Sony Indextron is a resistive load at this point, even though I fixed it by getting the components replaced and the solder joints redone, it's heating up like nothing else, that's the substrate. For the little wattage that Apple II has, lower than 50W, I would rather make a power supply with mosfets and have a USB C on the back of the machine, with a PD trigger. The machine takes 12V, you would only need to regulate 5V. How much does it draw from 5V? About as much as a phone, prolly 10W. That's a mosfet with a small heatsink and 2 or 3 10V 470uF caps. It'll never know there isn't a fully fledged PSU installed.
What's running on your Apple IIc in the background?
Sweet repair job.
My RIFA cap exploded in my ][ plus and instead of removing it I powered back up and played Choplifter.
With all due respect, miss, I wanted to say that you are so charming and adorable.❤
This is the first video I've seen from your channel and I loved it. I signed up.
I guess you figured out the Saturn clone doesn't replace the Extended 80 Column card. You need to keep that.
Hahaha yeahhhh I do need that !
Great job... subscribed!
Yea!!!!! More AWESOME content!!!! : ) !!!!
Most excellent! :)
That is ultra-cool.
I know it's been awhile since you did this video but I was wondering if they forgot to include those wires that you had to splice or did they not come with the kit?
I think they forgot them in the kit.
You can also replace the disk controller with a Yosemite new card.
love the video and I am glad you ditched the scotch clip!!
Great video!
Thanks!
Awesome video Ma'am,
Love it that you show the whole process including the oops-parts. Lot's of RUclipsrs leave those parts out witch is really silly.
In that way, they deprive people of learning from mistakes...
Also love your Macintosh earrings btw 🙂
Cheeeeeeeeeers
Jecepede
Nice!
Banging song
8:10 Thanx 🤣
.. on your new power supply that hot component is probably a thermistor, not a capacitor.
It's to protect components on startup.
Very nice. Just found your channel and I enjoy your bubbly personality.
I want to mate some wires with you and my Apple ii jplus 😆
awesome 👏
The RIFA cap has nothing to do with power going into the computer. It will do nothing in your blender example. It is only there to stop AC line noise coming FROM the computer...i e upstream. It's also arguably unnecessary now as three are no more NTSC analog broadcasts...but the HAM radio guys will get mad. But there is a lot more to make them mad like LED lights, TRIAC dimmers, HF florescent, but that is another story.
Also, the "other" caps Apple used (electrolytic) are of such high quality, it's rarely worthwhile to change them. I've repaired many Apple ii power supplies and found very few caps out of spec. The RIFA and maybe c3(next to the transistor) should be changed due to heat. Leave the rest alone. More than likely, they will probably outlast any replacement cap you put in, esp. Chineseum ones ...
I've repaired a couple of hundred and the caps do leak and fail and its not uncommon. Finding high quality replacement electrolytic capacitors isnt hard, both Mouser and Digikey carry a wide selection of Nichi and Rubycon caps
Was that Haro from Mobile Suit Gundam on the shelf?
Yes! I got him at the Gundam cafe in Akihabara a long time ago :) I was a big Gundam fan as a teen
I really like that rainbow stripe desk mat.
Your knowledge is so very attractive 😍
Blender 0.1 would run hahahahah
Sorry… Yellowstone disk controller from BMOW.
The multimeter joke. 💀
Haha. . yoink on them. American technical term?
健康に気をつけて 無理しないで がんばってほしいです。
Its an old computer...power supply is simple and can be repaired and maintained easily...will you also put a new mainboard because the original is old? I have an idea, just use emulators and dont even deal with retro hardware...because retro hardware fails a lot and fixing it is part of the fun...that is no longer an apple ii sorry cant watch this...
I'm not going to lie, this video thumbnail is hot. I know it's taboo to say it, but sue me. On another note, I hope you and Sean work on a collaboration vid, that would be super cool.
Why would you replace a power supply that is easily recapped and has worked flawlessly for over 20 years? Modern power supplies have proven to be unreliable under the best conditions they often barely live past their warranty and do extremely poorly in an ventilated enclose like the apple PSU case. Currently there are a lot of people that still repair the original PSU's and many on facebook that will guide you through the process, there is nobody repairing the PSU you put into it and no guarantee there will be a replacement in 10 years time, let alone 30. This video offers the worst advice I've seen recently.
Hey! Thanks for making the booti card!
A little dramatic, but I agree with you. However, I will say a super loaded up iie is close to maxing out that power supply, so I can see that as a point to changing it, but I certainly will not gut it.
Also, if the RIFA cap pops, just leave it alone. It will bother nothing and that thing is arguably unnecessary anymore with not NTSC broadcasts.
Speaking of the RIFA cap, it's apparent she doesn't understand properly what it is for by her blender example/comment.
I agree with you even to the point of not recapping...I've been screaming for years that the cheap Chineseum caps people are putting in will not last the ones they are ripping out! But people hear the RIFA cap pop and jump on the stupid recap the whole thing bandwagon. Sometimes c3 around the transistor gets cooked and should be checked but that is it ...
I have never seen a woman that's like you, a smart girl that like things men usually would do, Wane get married?
