On Klipsch Choprus speakers there is a little dinky 68uf electrolytic which does not last as long nor sound as good as an Audyn 68uf poly cap. Of course the size is 20 times larger at least.
I take the old electrolytic off and reuse the holes in the PC board for the new cap leads. I have to mount it on top of the board pairs with hook and loop tape and then a cable tie over cap and tape for extra security. I have to extend the leads to reach the PC board holes with good tined buss wire which is then insulated with teflon sleeves and the bare joints where the buss wire is soldered to the cap lead wires is protected by heat shrink tubes.
