I just put the last refurbishing capacitor in the outguard power supply board. >:D Yes, I should go bend a proper bracket or 3d print one, but... :-DD :popcorn: |
| EE4all:
In all seriousness though, if one does this with just a strap, it should be something more akin to thick rubber, so that if the capacitor ever swells, it doesn't start to stress the board. I have seen it like that, for example, in Fluke gear. |

I would just buy a axial cap |
| EE4all:
Naturally. However, a capacitor that big with wire leads needs to be secured, radial or axial type. HP apparently secured it by adding a piece of thin foam on top, so that the cover would sandwich it to the board. The new capacitor is not that big around, and I don't like just sandwiching things. |

with axial capacitors you can just put a bead of adhesive under them and its away from solder joints and you can slice it off easily to remove drilling holes in a 8.5 digit meter is not my style, its both insulting and provocative plus, in that meter of meters, I think you want the shield of the cap to be as good as possible, and use axial. you can still fix it with dp270, fiberglass shred and a axial capacitor Like if I got that from you I would probobly patch the hole lol you know with a axial cap, the case typically has spot welded lead on it, the negative side. I think there even exist some reverse polarity capacitors that have positive case, for negative rails, so you have the case tied to earth. its like bypassing shielding |
