A600 Capacitor Replacement
Hi all,
I am going to replace all my capacitors on my A600 and am looking for the names of places that sell them.. (not digikey please). I tried Amigacenter france and he wasnt interested in selling me any. Anyone know a place where i could get them all without buying a few here, there etc. thanks |

Greetings,
Don't go to a shop dedicated to hardware, especially not OLD hardware, they will charge an arm and a leg for nothing more special than everyday stuff. There was a reasonably recent thread about cap replacement, someone found some special types that are especially resilient. Find a good electronics store in Thunder Bay, if they don't stock them, ask them if they will, or find out somewhere that will, even get them posted, they're not heavy and won't cost much. Paul |

Thanks Akira,
I found this type of replacement electrolytic, specs look fine to me, anyone any thoughts on these ? http://www.niccomp.com/catalog/nacew.pdf As i remove the caps i will measure the capacitance and see just how far astray some of them are off tolerance. the A600 has.... 4 x 10uF Aluminium 25V SM (surfacemount) 5 x 22uF Aluminium 25V SM 2 x 47uF Aluminium 16V SM 4 x 100uF Aluminium 6.3V SM 2 x 1000uF 10V electroylic through hole 2 x 470uF 16V electrolytic through hole Edit. by the look of things a lot of vendors wont touch small orders.. I plan on getting enough to to 3 A600s and 3 1200s. Is anyone interested in buying a set of caps for their computers ? let me know... and soon cos i am so impatient lol Last edited by kipper2k; 16 April 2009 at 20:41. |

I hate potatos and shirts

Remember that two of those 22uF capacitors are for audio out, and C= make a never corrected bug on the design (!!!!!!) and all Amiga boards have polarised capacitors on an AC line(!!!).
![]() So, two of the required 22uF need to be no-polarised units (no need for SMD units, BTW). ![]() |

Which ones are these? Can ANYONE ever reply to my original post saying which are the caps to replace and what to look out for (like what rkauer helpfully pointed out now)? No matter how much you guys write, I have no idea of what you are talking about, but if you show me a picture, I can guide a technician on his way to repairing my Amiga properly! I have my A600 sitting there gathering dust and cap acid just because of this ![]() |

capless A600 board.
Here you go Akira, heres a link to the a1200 and A600 schematics, using all the info on this thread your tech should have everything he needs
http://www.devili.iki.fi/mirrors/4x4.hopto.org/ ok, heres where i am at. I removed all the caps except for the audio caps. All caps except for 3 were in the 5% tolerance limit C306 = 9.2uF (should be 10uF) C612 = 8.0uF (should be 10uF) C409 = 85.8uF (should be 100uF) looks like a bit of board damage underneath c306, cleaned up good, doesnt appear to be any trace damage. Overall the board looks good. Also notice i removed quite a few of the PLCC's and cleaned up those traces too. I have ordered some 44, 52, 68 and 80 pin PLCC sockets. i dont know if this will ever work again but i've had some fun doing it. Heres a pic, if you want to see see the hires pic then click on the link. below. http://www.kipper2k.com/amiga/caplesshires.jpg ![]() Last edited by kipper2k; 17 April 2009 at 02:08. |

Hi kipper2k,
I think that board looks very nice indeed. It seems like you made a good job of the clean up. I'll be very surprised if you can't get it working again. Well done so far, mate! ![]() prowler |

It;s caps death, I noticed at least two caps leaking, the symptoms are the typical, booted up once and never again, dont want to keep trying!
I guess I'll have to trust Mr. Technician. I'm really careful because this computer has been with me since 1992! It's my original Amiga ;_; |

Find somewhere reputable and close, convey a sense of price isn't the object, perfect quality is, they'll charge an arm and a leg, but they will most likely also take extra time and care. If they say trust us, don't. Paul |

Did you zap the board with static? or was the Amiga still closed up when it refused to boot up again. ? I have to wait for spare parts for mine before i can start work on it. If you want to send it to me then i can give it a shot... shipping costs would be high if you sent the whole computer so it would have to be just the board wrapped in bubblewrap and cardboard to protect it. I've received boards like this all the time and never had a problem yet. The longer the acid is on the board, the more of your traces it will eat. Because i'm way up in Churchill Manitoba shipping is about 8 - 10 days from USA so its that that fast of a turnarounf |

Such thing does not exist in a humid area like here ![]() nNo, the machine just doens't work, and it shows typical signs opf caps death, black screen with the capslock blinkng etc. And as I said i confirmed leaking acid from at least 2 caps! It's been in storage for many years without being used. |

I am ordering new capacitors for both the 1200 and the 600 tonight. i'll order enough for 5 kits so if you know a local tech then i can send you a kit.
I'll post the part numbers for digikey in a bit if anyone wants to order their own cap kits Last edited by kipper2k; 17 April 2009 at 03:52. |

Hi All,
