Whats a beak head plier?  Do you wiggle it back and forth?  I have already replaced 5 caps in my computer with lifted pads on 4 of them.  Probably corrosion :-D.  Thats my story and I'm sticking to it.  Wasn't too hard to fix but I would rather not have it happen again.

Update: I feel stupid.  Of course I know what a beak head plier looks like.  I know what it looks like but not the name, if that makes any sense :-)

A1200:

5 x 22uF, 25v (or 35v)

2 x 47uF, 16v

4 x 100uF, 6.3v

3 x 10uF, 25v (some have 4)

The thru-hole caps are 2 each 470uF, 16v and 1000uF, 10v.

Quick question can i use 100uf/16V instead of 100uf/6.3V?
Or in fact can i use higher voltages then the ones noted down?

You can use higher voltage units, but notice then you'll grab bigger ones.

 As a rule of thumbs, the bigger the voltage accepted, the bigger the capacitor's case.

 But remember those old capacitors had a bigger case than the up-to-date units, so the "next higher voltage" will use the pretty same case as the old, lower-voltage, one.
Goodbye people.

I\'ll pop on from time to time, RL is acting up.

Hey D, might I be able to take you up on your digi-key parts list?

It seems my shift keys stopped working / caps lock light stays lit on the a600 so I have some cap replacin' to do.  :-D

Whats the easiest way to replace the SMD capacitors on a 600.  Some of them are in tight places.  Is there any way to maybe snip them off without hurting the motherboard?


i also damage some tracks when changing capacitors ( now repaired ) then discovered the best way for me is to get a small cutting tool and cut the old capacitors in half,setting the cutting tool @ very low rpm then desolder it.

Something to remember:

Electrolytic caps have a specified life of only about 20 years. Some will last longer, some a lot shorter.... but they will all fail eventually. That's why people replace them with tantalum bead caps, which have a much longer life. For CBM, this would have been prohibitively expensive, as tantalum beads are a lot more costly, but for us it's only the matter of a few quid/dollars/beads.

If you replace electrolytics with electrolytics, you'll have to do the same repair later on, no matter what brand you use.

This is worth bearing in mind for all appliances... I recently fixed my turntable (a Linn Axis) by switching out four large electrolytics..... so if something stops working, they're often the prime suspects!
