Dennis I just finished doing that mod this morning getting ready for field day. I'd like to tell you was easy but it's not. I'm a professional so I have all the tools. It took me about three hours. I could have done it a lot faster but I was extra careful not to drop hardware or leave soldering debris. The problem is the board is designed for machine assembly and soldering using a paste. The holes are small and almost padless. It took several squirts of flux and two soldering irons to get the holes clean and then the choke barely fit. It's a long way from your hot water 100. You have cause for concern. 73 Fred, AE6QL

Haarsager Sent: Thursday, June 21, 2012 11:19 AM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 12VDC OUT current modification 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!
