The value you wrote, 4.7 uF 25 Volt / Non Polarized, is a common capacitor. Many of the electronics parts dealers can have this type of capacitor.

If you want to be fancy, you can take 2 of 10 uF / 25 Volt capacitors in series. Put them back to back with the two negative leads joined, so that you are left with the positive leads. In theory this will work, but in practice with some circuit designs, this approach is not a very good solution.

Regarding: "4.7uf 25v non-polarized electrolytic capacitor of handy t.v.,"

Never ad-hock something together when you can get the equivalent OEM part from a multitude of suppliers. For example:

Note the far left-hand side of the window:

Bi-Polar/Non-Polar Electrolytic Capacitors

Literally, pull the menu selection down as to what you need and presto, see if they've got it in stock and sell in single quantities.

Incidentally, Mouser is a premier components supplier for the entire U.S. If they don't have it, they can get it, if they can't get it, they'll [typically] tell you a manufacture to contact.

Their catalog is about the thickness of the yellow pages for a large city. When you call them, request that they send you one. They also offer that catalog now days on CD ROM. Your choice.

When posters don't include their location it makes it very difficult to give information about where to obtain parts local to them. It is often uneconomical to buy a single part from organisations such as Mouser using their shipping service.

While I agree that folks may be posting from anywhere on the surface of the planet, and sometimes I wonder if not beyond, Mouser will ship just about anywhere and there is no minimum order. I grant you that shipping costs is a factor on any item mail-ordered these days from any vendor. But not everyone has the luxury of having the exact OEM part in their local geographical area. For me personally, I've got a Fry's Electronics in my city but, as usual, they're either out of (empty rod) or simply don't carry the correct value. When I work on other people's electronics I do not compromise the design by pasting together two (or more) parts or put in a 'close' value. I take the extra time & effort to find the correct part and install it. It tends to keep nightmarish episodes and later questions from occurring as to why I didn't stick to the parts that the factory installed.

While there has been exceptions to the above 'rules' they are rare since I tend to stick with the original values. On the rare occasions that I do deviate, I let the owner know beforehand and fully explain as to why. A recent personal example is the motherboard that I'm using right now was recently given to me by a good friend since it kept resetting. The notorious Taiwan GSC electrolytic capacitors where the electrolyte formula had [supposedly] been stolen have been replaced and all is well. Did I deviate from the original values - no.. Did I order from Mouser - you bet! In the process, I ordered some 5mm L.S. electrolytics when I actually needed 3mm - my mistake. I called them, explained it, they said NO problem and sent me the 3mm parts at no charge - when asked, they didn't want the originals back. At this point, I'm happy with them even though I've dealt with, and been happy with, others such as Jameco also. I just find that after looking through their 1,940 page catalog, they tend to have the exact replacement of what I'm looking for. As long as I can order *exactly* what I need in single quantities - I tend to do so..

The OP's posting I.P. checks out as Pakistan....

And I thought it was only North Americans who thought they didn't have to say where they live. ;)
