What kind of problems are you having with them?


I just received an e-mail back from that Charles guy. Quick response I must say! :)

 Anyhow, all four of them have audio issues. Crackling and all that jazz. The PAL 600 needs it's PCMCIA port replaced. The NTSC 600 needs it's IDE port replaced. The PAL 1200 just needs recapped as far as I can tell. And the NTSC 1200 needs it's kickstart sockets replaced...

...a result of me trouble shooting a purchase from Amigakit.

My eyes need some work. I have worked much on hole thru replacement, Surface Mount is out of the question for my eyes right now.

Is there a  list of good cap manufacturers sites? :)

Funny, they mentioned the lack of a "good list" in that very forum. :)

The audio problems you're experiencing could be caused by bad capacitors and/or electromagnetic interference.  Check for any bulging caps and for any brown rust-like material on, under, or near the capacitors.  Not all capacitors that have gone bad will show physical signs, but it doesn't hurt to check since it is a sure sign that they have gone bad. The IDE port is easy to fix and the PCMCIA isn't that hard but takes more time.

Also, bad traces can also cause problems, especially on older motherboards.  If you have a USB microscope and a multimeter, look for any corrosion and check the continuity between traces.  Even if there is a loss of connection between traces due to corrosion it is still possible to fix it.

I'll admit that link isn't very helpful since some people are selling fakes of good brands. What you want are Japanese capacitors.  This might be of more help: How to Identify Japanese Electrolytic Capacitors

Indeed, the A600 that I waited 3 years to have recapped also had bad traces. Since the IDE port on it is screwed though, I've not had a chance to test the audio yet. :)

Needless to say, the prices I've been offered for repairs on all four boards are most certainly within my ball park. I do believe I shall have them all repaired, then will probably part with the PAL boards after I get them back and have tested them. Considering I can have everything repaired kind of makes me want to have a 600 and 1200, fully decked out. It will be like having two new units... or so I hope, in which case I need not worry about FPGA for the moment.

Alas, one of these threads paid off! :)

This is the second or third time amiman99 has saved the day for me.

I'd be better off piecing things out and making some cash as opposed to shipping my goods to Europe.

Yes - of course. You would have to be afraid we implemented some spyware - as a sort of revenge for the NSA activities here...

I hear you man... my ancestors are native after all. Believe me, that history is still very much alive and well as far as I'm concerned. Though with the NSA and all this jazz...

...I really don't think America is the center of it all, I believe the power has always been more of a Global nature, though like The Phantom Menace or politics in general, America has became the front man to take the blame. I mean haven't you noticed that everything is anti-America now a days, even though the rest of the world that is in bed with the U.N. is guilty of the same practices. I mean didn't Britain drop an atom bomb of their own, but no one ever talks about that.

 I have no love for political empires, no love for the new world order, or religion as an institutional power. So from where I stand, I have nothing to do with any of that NSA B.S. or anything else being reported on osnews.com.

BTW, how's the EU feeling? Like those cameras down your back on every street corner? Can't say I'm looking forward to the American union my self not to mention all the cameras that have began to show up here either.

 Anyhow, I'm going to bury my head back into my Amiga now. ;)

I've shipped out to this guy:

His communications are great and he's only 2 hours north of me, win win!!! :)

I just sent out four A4000D (B) motherboards to Anthony Hoffman in Christchurch, NZ with various problems this past week.  With USPS Priority Express ($83 USD) it will likely take two weeks to get there, but his website (http://amiga.serveftp.net/) makes me think that I'll get a good evaluation and repair done on them.  I'll report back with times, costs, etc.

I'm sending them as I can afford to get them fixed, so so far there is just an A600 on it's way.  And yes I shall be sure to come back singing his praises very soon me hopes! :)
