I think this capacitor may fit into the C9 and C13 area next to the
headphone.  This is an only 10V cap rather than the 25V cap that
Elecraft has in there now.  But I think that should be plenty of
derating for a 105mW power amp.  

So if anyone has a pair of calipers and their radio open I'd be
interested to see if we think this thing will fit.

The bottom pad in the direction other than that with leads is ~5.3mm
or .208" and in the direction of the leads its going to be ~5.5mm
or .217 inches to the outside of the leads.  

Would greatly appreciate if someone would confirm this for me.  I
remember taking these measurements but didn't write them down.  I
believe I'm remembering them correctly.  

Anyone else have any thoughts on if 10V is going to be enough?  I
figured 10V^2/16ohms is about 6.25 watts and being that the amp is
designed to deliver 105mW to that 16ohm load that seems like it should
be more than enough derating.  Any other thoughts?
