Hi, my first port of call would be maplin.co.uk they carry a large range of caps. I've found them very helpful in the past, if they can't supply, they may be able to point you in the right direction.

When I remember correctly, the capacitor which fires the shutter in the X-300 is 4V/220microfarad. The standard ELKO at 6V is probably to large to be mounted in the camera. Try to substitute this ELKO with a Tantal type ELKO, which is tiny and will fit into the gap in the cameras body. Check polarity, you do not replace a capacitor but an elko. I hope I was able to express my thaughts clearly using my bad english.

hi,thanks for all your advice,ordered a pack of 10 from micro- tools,it says for x700, but i think they will be for x300 also,anyone fitted these?please advise.
cheers,kenny |

Like he said, be sure to get the polarity (+/-) correct. A backwards capacitor can burn and do other nasty stuff, though at such a low voltage it's more likely it just won't work right. Other than that, it's just a mechanical job of fitting it into a tight space, and making good electrical connections. You do know how to use a soldering iron, right? |

hi,took the bottom plate off,the right hand wire is greenish and there is a gap where it goes into the capacitor,so it does look like thats the problem,i havnt used a soldering iron since i was at school,over 50yrs ago,any tips on getting the right one for the job,cheers |

You don't want to use anything too large, both physically (tip size) and too hot. I'd say something in the 25-40 watt range would be about right. (You can actually cause harm by using an iron that isn't hot enough, since it'll take longer to heat the parts you're trying to solder and could fry something.) And use a soldering iron, not a gun.
The key here, as in so many other areas, is cleanliness: make sure the tip is clean. I just use an ordinary sponge and water. Tin the tip (melt some solder on it) before soldering. And be sure to use electronics solder (rosin core), not acid core stuff made for plumbing! Other than that, it ain't rocket surgery. If in doubt, practice on something outside the camera first. |

Soldering: David postet a lot of hints you should consider. Be careful with the contact points on the circuit board. The circuit is printed on a thin flexible foil which is not this heat resistant as the pertinax material you may know form your last soldering work which was in the 50th! Personally I prefer old electronics solder (before 2000) because the new material is lead free and its melting point is higher.

Too late now but I posted info of a UK supplier in a previous post at https://kyp.hauslendale.com/classics/forum/messages/2/15219.html
I've also got a few spare if anyone else needs one. |

hi all,well ive done it,using paper clips to keep the capacitor in place,a small piece of cardboard for a firm base i soldered the new one in place,the camera now works fine,thanks for all your advice,
cheers,kenny |
