Re: [Elecraft] K3 12VDC OUT current modification...tools
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. Hi Fred all you must have been missing the one tool which made it easy my good ole Hakko solder sucker, which i bought before swapping all the crystals in the K2 crystal filter. I opened up the bottom , top back Fan assembly. From the bottom, with the set upside down, let the Hakko do it magic on the four pads, which dropped the two parts on the table then inserted the two new parts,,,resoldered,, lids closed. bill ny9h/3 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 12VDC OUT current modification...tools
Fred, I put one in a friend's K3, and it only took about an hour. Most of that time was in removing the PA assembly and putting it back. The components were removed by alternately heating the ends (one at a time) until they cold be flicked off the solder pads. I have decent mobility and good solder/de-solder skills. So if you have problems with arthritis and poor eyes and drink a lot of coffee, it may be wise to let someone else do it for you. Do you have any capable hams nearby that might give you a hand. 73, Don W3FPR On 6/22/2012 2:47 PM, Fred Townsend wrote: Please see comments below. -Original Message- From: bill ny9h [mailto:n...@arrl.net] Sent: Friday, June 22, 2012 8:33 AM To: Fred Townsend; elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 12VDC OUT current modification...tools I'd like to tell you was easy but it's not.
