    BGE's take on the Quadra 900/950 ATX PSU Mod

    How difficult was the surgery? I have it all ready for me but I just haven't felt the urge to sit and tackle it yet. Ive watched enough videos, I think I got a plan but I am not very experience with this kind of soldering. I got to get this done one weekend soon. Any tip or suggestions for me?

    Ahh ok very cool. I definitely want a parts kit too when available. Thanks for all the hard work to keep these old beasts alive!

    BGE: Sorry, I haven't been following this thread closely as I should have been. Are you offering to sell PSUs or the parts and instructions for us to mod our PSUs?

    BGE's take on the Quadra 900/950 ATX PSU Mod

    So I had the same thing happen to one I just got in the mail. Please see my threads... You should find these helpful. I was able to see the remnants of markings on my burnt cap and was able to determine it was this: https://www.ebay.com/itm/10pcs-T491C106K016AT-KEMET-Tantalum-Capacitor-16V-10-10UF-SURFACE-MOUNT/313012284846?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 I ordered it and soldiering station but I have not replaced it yet. I did retrobright the plastic pieces of the case and they came out really good. Putting out a blog/video series on it which I will post here and r/vintageapple when complete. Hopefully its done this month or next. As far as BadGoldEagle's PSUs, I would really like to get one but I THINK mine is working fine. I spoke with someone who is electrical engineer who does not think my PSU blew it. I hope he is right. Please let me know how you repair goes and I will you too!
  5. Oh great tip on the magic eraser. There is a big black scuff down the front, I'll try to remove it with that. I don't think I mentioned before, this 950 has a Metroworks inventory sticker on it. Im really anxious to see whats on the hard drive. Maybe theres some cool code from some product on there. Long shot but even it was marketing there could be something neat.
  6. Yes good call. Will do. This thing may just come together after all. Thanks.
  7. Thanks Alex. All this has been very helpful. I think I'm on the right track... now I just learned I need to watch for two things, the pads and the size of the new cap! I will get on it! Now the only remaining question I have which you may not know the answer too is, I want to clean the case while its apart and retr0brite it but its dirty. I want to stick the case in the dishwasher to clean but I don't want the hot water to melt or warp it. I don't think it will as I've done it with many keyboards but I also cant risk my rare baby like I can a keyboard.
  8. Oh wow. Thanks for that. Glad to know theres someone who's been there before. So you replaced the cap and thats all? Several folks have told me to take off that voltage regulator right above it and test it as it may be the cause. I understand why they would suggest that but I want to do the least amount of work possible here, not (only) because I'm lazy but I don't want to mess anything up. Im no expert with the soldiering iron and I don't want to do more harm than good. The cap being surface mount, I think I can handle that. As far as the cap goes, I believe C26 is a 10μ 16V F2. If you can confirm that, that would be great but it is behind the PSU so I don't expect you to disassemble the whole thing unless you want to! haha
  9. Ok, I'll see about getting some distilled water to do it. Now the other part, what to clean it with. I have a medium toothbrushes I could use. The cloth like paper towels will rip. Cloth will get caught on stuff and I don't want to pull anything off or otherwise put strain on it. Some of the components are hard to get in-between. Im guessing the toothbrush is the best bet? Then dry for 48 hours.
  10. I don't want to buy an ultrasonic cleaner. Is there a certain type of business that has these, even if for cleaning other things that I could see if there is any in my town. Do you provide a cleaning service? This is a big board, I just looked up the cleaners and I don't want to spend that for one board. I do have a pm6500 and pm8600 that power on but no chime. They need to be cleaned too but Id rather pay someone to do these than buy the machine and shelve it after these few are done.
  11. I acquired this Quadra 950 from a guy on reddit who cleans out warehouses and he posted on reddit, I made an offer to ship it after some preliminary photos. It was a good deal so I got it. Its quite clean considering it was stored for many years in what I believe was non climate controlled. Some spider webs (a couple spiders, dead) inside. Has the residue all over which indicates its been in humidity for a while. But other than that, good condition. You may have seen my other thread about when I fired it up, a cap blew and I'm in the process if information and part finding to fix that. I have it totally apart now so Im going to give it a shot to retrobrite it and clean the rest. The Case: The case is in good shape, minimal dings and such. A couple parts have yellowed but not too badly, the main part of the case isn't that bad. One of these days I'm going to use 8-bit guys method to bring the color back. But before I do that I'd like to clean it up good. I was thinking dishwasher for the plastic parts but I'm afraid the heat could melt the plastic. Does anyone have any experience or recommendation on cleaning the case and case alone in the dishwasher or otherwise? The Boards: I have some photos for specific questions related to the boards. I started trying to clean it with alcohol and toothbrush but its really hard to get in all the nooks. A lot of components are really tight on this board. I searched but found a lot of conflicting evidence on putting the boards in the dishwasher. I don't know how much risk I want to take with this board. I feel like I got a great computer for a good price and I really want to get it working. I cut my teeth on a Quadra 950 video editing and some (very basic) 3d modeling in middle school. It really felt like we were coming in to the future and I want this computer to be my throw back to that. Attached are some close up pictures of the dirtiest spots on the board for reference. Pics of the case are not needed. Worst case I'm gonna hit those with the hose if the dish washer isn't recommended. Thanks in advance for any direction.
  12. Oh I see. I dont want to remove anything I dont absolutely have to. I understand this stuff at a novice level and have dont simple solder jobs (poorly I might add) and I really dont want to damage this thing any further. Today I spent time reading and digesting Trag's post on the SMC capacitors he has for sale and soldering tips. I feel like I can safely remove the burnt capacitor. I may be confident enough to replace it as well but I'm going to have to practice on some old worthless boards laying around. I dont know if I should go that route or find someone to do the job properly and pay them.
  13. Very helpful. Thanks a bunch. I will get to work on it this weekend hopefully.
