[Elecraft] Quick Question for someone with their radio open

[Brett Howard]

Take that back... Looks like Mouser's website was lying that that was a
5mm diameter cap....  Its actually 6.3mm which is going to be too big...

So I did a bit more digging and found:
http://mouser.com/Search/ProductDetail.aspx?qs=sGAEpiMZZMsCnlYck6hSqLKeSeHnSOGyVYzpVBYnbJA%3d

Looks like this specific cap should fit the pads.  Providing the .208"
measurement that I think I remember correctly isn't way off in left
field... :)

If someone could verify the dimensions of the plastic nugget on the
bottom is about .208" x .208" then I think I'll have to order me up a
few of these.
