Dan, WG4S, picked up on a mis-statement in the message below about the color code. It think it's worth repeating here.
He pointed out that calling the last color or digit a multiplier is incorrect. Multiplying any value by zero results in zero! He's perfectly right. What I should have said was that the last color or number indicates the number of zeros following the value. So 820 means 82 followed by zero zeros = 82 pF. A value of 821 would mean 82 followed by one zero = 820 pF and so on, just like resistor color codes. Tnx Dan! Ron AC7AC -----Original Message----- VA3IMO wrote having difficulty with finding C71 and C174. I had the same problem. In my kit the 82 pF were labeled as "820" but the manual lists them as labeled "82". The same thing occurred with C122, a 56 pF, labeled as "560" but manual lists as "56" I don't recall the part number but I think there was also a "561" labeled cap...I had to do some resoldering once I found out... John AB8O _______________________________________________ What's happening is that some capacitors are labeled with their actual value, e.g. "82" for 82 pF. Others are labeled with the numeric equivalent of a color code, including a multiplier. On those an 82 pF cap would be "820" meaning 82 and a multiplier of zero just as an 82 ohm resistor would be coded gray-red-black for "820" = 82 ohms. How the parts are marked may change during the life of a kit as new stocks are purchased, and a new marking may not be picked up in the manual. That's why it's nice to have a DMM with capacitance measuring capability to check caps below .001uFd. Lacking that, doing a complete inventory will uncover these issues before they are soldered into the wrong positions. I recommend taping the parts to cards or sheets of paper as they are identified, each part marked with the proper reference designator next to it on the page. That way you will find any discrepancies very quickly. And during the build it acts as another check to ensure all the right parts go in the right places.
