[Elecraft] K3 12VDC OUT current modification

[Dennis L. Haarsager]

I just received the P3SVGA option for my P3 and see that it either needs a
separate 12VDC source with >= 700 mA current or installation of an included
current modification that raises the K3's 12VDC OUT capacity to 1 A.
Frankly, component level work on the K3 scares me, since neither my eyes
nor hands are as good as they once were and the last kit I built was an
HW-100 44 years ago.  I do have an ESD-safe soldering station and can
easily acquire some de-soldering tools, but can anyone who's done this can
give me some level of comfort that it's possible?  If it's risky, I'll dust
off an old 12V supply.

By the way, the $400 I spent on the HW-100 Heathkit by the CPI is the
equivalent of $2,590 in 2011 <http://www.measuringworth.com/uscompare/>, a
bit more than the cost of an assembled K3/100 today!
