How reliable is cross referencing parts?

Hi Canti,

This is off topic, but I can't help appreciate the close up photo - good details, good lighting, even the ridges on the solder mask show well. It's not too often to see good photos posted on forums.

Can you please give us some details how you made this one? camera, lens, a few tehniques how to make a close-up shot? Did you make some editing?

Thanks!

If you need to take a good Close-up Picture of something, put a pair of "Reading Glasses" Directly in Front of the Camera Lens. (Tight to the Camera Lens)

Using a 2.5 Dioper reading glass will give a Focal Distance of about 12 Inches. and if your camera has an Optical Zoom, put it to ful zoom for best results.

(A 1.5 Diopter will be about 16 Inches Focal Distance)
(A 3.5 Diopter will be about 5 Inches Focal Distance)

Thanks for the compliment, but I just started in the photography game. I can't remember if I did anything special to get that kind of close up shot, it's been a while. I think I used the macro feature of my Nikon D80 camera, sorry like I said its been awhile. The only editing I did is croping it using PS CS. Sorry I couldn't been more of a help.

Thanks.

Don't test it, replace it!, it's under a fair amount of strain, in a hot environment, and is a common source of problems - for the cost of a small electrolytic (and make sure to use a 105 degree one) it's not worth messing with.

OK, I'll do that, but just to entertain me a little how would I test a capacitor. And as far as replacing want should I look for as in specs and value?

Thanks for helping Nigel.

You would use an ESR meter, a capacitance meter wouldn't be of any use.

To replace it use one the same value, and the same or higher voltage, and like I said before, use a 105 degree one (not the poor 85 degree ones).
