Acill's Amiga Repair Thread

[Acill]

I'll be heading home Saturday June 25th from vacation. For those looking for repair services feel free to contact me.

Acill does excellent work and has a very nice work studio and workbench with good equipment. He cares about the job and does the best he can. He capped a 3640 for me and repaired a video card with broken cap. Thanks! Good work!

More progress on kreciu's A1200! The new power connector and filter coil came in so I installed them this morning. So much better than that mangled mess! See the before again and the after shots.

Before:


And as it looks now with the "New" parts:

Nice work ! Where did you get the power connector from, I think the counterpart, the plug, is not produced anymore right ?

New old stock from a friend in Sweden. I have one left and also one of the other end a well. Only other option is from an A500, 600 or 1200 that is dead beyond repair to use as a donor board.

Thank you. Now I need to finish my case "mod" and my A1200 should be good few more years.

Well I did the best I could with this one. I hope its good now! As far as I can tell everything is working as it should.

Another side project I did for kreciu. This is a Mac Color Classic board. It had very leaky caps. Once I started removing them I discovered two pads that were only held on by the old solder and some junk on the board. Also one cap started to eat away at the board as seen in the first picture. I had to fix them by routing the ground path to another section, but it worked.

Bad spots and missing pad:


After reworking and a recap, the shorter one here isnt ideal, but it works.


This is another reworked area. Fortunately these two caps share the same ground :


The completed board:

I think it is important to add few things. I used this mac just before sending it to Acill, there was not any issue with it. It worked fine, boot without problem, I could use it. I also looked at this mobo (maybe not very careful), and did not see and damage from leaking caps. I send this mobo "just in case" and I was already to late. This Color Classic was a gift from friend, and was not used for about 10 years or more. Lesson learned.

Leaking caps are not easy to spot all the time I have found. At first glance I was going to say this board was okay until I noticed the one spot of corrosion on the board and a lot of sticky dust around the cap. Once I pulled that one of it was clear it leaked. I have included all the caps I removed so you can see the leaking ones as well. It was all under them, and still early enough that it only caused minor damage.

Some progress on Kremlar's A1200 for you. Foil taped up and caps are removed. Up next is the removal of the RF modulator. I should have this one done tonight with some luck. Its very clean and problem free so far. This is one thats been taken care of and being recapped before it was leaking!

[Kremlar]

Yay!  Was not so clean on the outside.  

[Acill]

Kremlar's 1200 is complete,  great machine to work on.

This A3000  was sent in completely filthy and needed a lot of recap and trace repairs. The Paula was soldered on very sloppy and had bridges all over it. I cleaned it up, fixed the poor cap work previously done and fixed the Paula socket as best as can be expected considering the condition it was in.

It should live a bit longer of a life now, hopefully happier than before!
