I have not recapped my AT "Magic Pack" unit but this mod was required on my AT unit when using an Indivision AGA scandoubler. My video would constantly blank in and out until the unit warmed up after about 2 hours. This did the trick....

At least we don't have that bad caps problem that plagued Dell motherboards about 10 years ago. I must've replaced hundreds of motherboards in OptiPlex 270/280-class systems back then!

I just replace the caps! (LOL - Hundreds of them - capacitors that is) Still an ongoing problem with Dell MB's though.
Replacing Dell MoBo caps is a cinch and cures all the "my Dell won't boot" problems! Good money too! :)

If the system is running fine and the caps haven't leaked or the tops popped up, then it's absurd to have someone open the system and have the board re-worked, unless you have more time and money than common sense. And board replacement is probably cheaper than having the caps replaced anyway, not to mention the down time waiting for someone with the solder skills to do the job.

Well, inspection is the key, of course, with electrolytic caps... If you see bulges or leaks... Capacitor Man says:
"Replace as necessary!"

That item hasn't been "in stock" on their website in years. Either way, they're still NOS 20-year-old parts that WILL develop the exact same problem. Also, A1200/A4000/CD32 caps are not the type where "the top pops", typically. Instead they leak from underneath, and directly onto the board. Do a google search on it, or whatever. Believe what you want, don't do preventative maintenance, and just spend your money on a new board that will most likely develop the exact same problem.

There's dozens of people all over the forums that do these repairs.  Prices start as low as $40. Again, not rocket science. Are you just trolling? Seriously this is the dumbest argument I've seen on here in... well... weeks? ;)

I just bought an A1200 re-cap kit from AmigaKit and it cost $10.00!

https://amigakit.leamancomputing.com/catalog/product_info.php?products_id=1137

They do issue a warning for the faint of heart, however...  :roflmao:

I bought the kit for my friends 1B MoBo as it's starting to act up.

BTW, Mike is right about the old caps not bulging on the top and WILL leak from the bottom. :(
