I tinned the traces with solder too.<\/p>\n<p>Then I used a solder gun to put the new piece in place. I think it looks pretty good. I will need to use a small washer on the other hole when I put in the new electrolytic capacitor so as to make the holes even and not bend the board.<\/p>\n<p>I found a new capacitor on the Mouser website and I have ordered it. That should come about the end of next week. Then we get to put it in and see what happens. I hope the rest of the thing is feeling healthy.<\/p>\n<p><a href=\"http:\/\/w0ep.us\/OM\/?attachment_id=3875\" rel=\"attachment wp-att-3875\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-medium wp-image-3875\" alt=\"85662B power supply trace repair\" src=\"http:\/\/w0ep.us\/OM\/wp-content\/uploads\/2013\/09\/GEDC0259-700x1047.jpg\" width=\"700\" height=\"1047\" srcset=\"http:\/\/w0ep.us\/OM\/wp-content\/uploads\/2013\/09\/GEDC0259-700x1047.jpg 700w, http:\/\/w0ep.us\/OM\/wp-content\/uploads\/2013\/09\/GEDC0259-684x1024.jpg 684w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>[Today&#8217;s run: rest day] Having the found a big problem in the power supply section of the 8566B spectrum analyzer, I worked quite a bit yesterday afternoon to get it accessible and repaired.
