I personally do not replace Amiga or any vintage computer capacitors if not required. My practice is to every once in a while (perhaps annually) measure each capacitor level with a multimeter. If I should see signs of age, I will replace, otherwise I leave them be if they show sufficient life left.

The reason for the above is simply due to minimizing risk of damaging any components such as the motherboard, solder pads, etc due to applying heat via a soldering iron, hot air, etc.

I am not saying the above is the absolute right way to go about it, but only what I personally consider to be the right thing to do, when trying to best take care of 30 year old equipment while assessing all possible risks of damage.

You cant test a cap with a multimeter, it will not tell you anything useful. The only way to properly test a cap is with a ESR meter and you would have to desolder them to do that.

soldering/desoldering caps is a basic,standard procedure in electronics, there should be no reason to cause damage if you are doing it correctly.

Sorry for the typo. Not a multimeter, but an in-circuit ESR capacitor tester.

OK. I know, it was asked for SURE by someone. Problem is that I like to have conversation with PEOPLE.

In next 10 years, we will have answers in google.com for every single question you (I) can ask EVER. Should you close "forum" section and tell everybody "go and search google library"?

BOOOOOOOORING.

IMO there is value in conversation, interaction etc. it is called learning process. It is like with school. ALL what we teach was already ANSWERED (I'm teacher). So, do you think I will tell my students: Stop asking questions, go to google and read answers? There are there for



Most likely I will do it, but now I want to know "what is best" for my few Amigas...




I agree with this completely!!  It can be just as easy to answer a question with an answer rather than sending people off looking for old threads.  It defeats the purpose of a forum.  Plus in rediscussing something some new info might come out.  It annoys me looking at a post and seeing the same old "we've already discussed that" answer.  I am normally looking at the post because I might be interested in the subject.  If you don't want to discuss something than ignore the thread.  It's really simple.

LOL.  You guys don't know how easy you've got it.  In some of the other forums I frequent they'll straight-up curse you out if you ask the same question for the millionth time, that was already asked six times last week alone.  But, cheers!  :D  :banana:

Edit - I've actually asked questions on some forums and had my thread locked by a moderator because it was asked too many other times recently.  Everybody's a tough guy on the Internet!  ;)

As I said, if you don't care to discuss something ignore the thread. Is post count so important that someone has to comment on every single thread when you aren't willing to discuss what the thread is about?  This site is going to die if everybody asking questions is told not to because they have already been asked.  In real life if someone asks you a question you don't tell him to go ask Joe the answer because you already answered it for him.  You answer the question again and move on.

The recap went well. Ran A-Train overnight and it was still running in the morning - and the bank balance had gone from $300,000 to over $1.5M! A little copper square fell out of the floppy and it was making some odd sounds and sending the power light into spasm when ejecting disks so I have purchased a new internal disk drive - nothing to do with the recap just bad luck.

Nice work!  Now while you got it open, just need to replace that RF output with an HDMI output.  ;)

That's motherboard butchery! I'd prefer to wait until wireless video transmitters are invented than butcher any of my Amiga motherboards. Each to their own though etc etc! ;)

You can always save the RF output to be put back on the motherboard at a later time.  I wouldn't really call that butchering the motherboard.  But as you said, to each their own.

This is especially true in case of Amiga. There is NO new hardware made so there is no new questions.

I had some break with Amiga, now I'm back at least for some time. I started looking at various Amiga forum and in general it is rather EMPTY. How we are going to attract anybody to Amiga when our forums will be dead/empty or you sent anybody who ask question to "archive" section of forum?

Technically I could ask this question about caps on any electronic related forum, but there is "something" about asking this question to Amiga users.

Also I DID some search before I asked this question and did not feel I got my answers.

When I re-cap my Amiga I will post picture, yes it is going to be ANOTHER BORING PICTURE of Amiga 1200 mobo with identical caps anybody can get of ebay.com. Wait! It is not going to be boring! IT IS MY AMIGA 1200 mobo!

I wouldn't throw away that old floppy drive if it was working before
recap.That little copper square shouldn't make a difference (I don't
have mine and floppy works 100 %).

Voltages from psu (knock on wood :roflmao:) or more likely floppy cable
connection maybe ?

Or just in case that square copper thingy was jumper you can go here to check jumper settings http://dliapp.wizhut.com/blog/?

Probably depends on your definition of EMPTY. I still find I spend too much time on my daily amiga.org fix.
Trust me...                                              I know what I\'m doing
