Not fully reading the directions before installing the component, I
immediately clipped off (at the respective holes where the two component leads were inserted) the leads after installing current sensing resistor R7 into the closest of the 3 holes on the two solder pads. Would it be sufficient to solder short pieces of the clipped off R7 leads to the two pads, from the innermost holes on the pads (where the R7 leads have been soldered and flush-cut), or do I need to remove R7 and properly install a new, replacement resister? Since, even thought there's plenty of electrical continuity, there's a physical discontinuity between the resister leads and the small clipped pieces of lead I've installed, I'm wondering if this is going to cause an electrical performance (or cooling) problem down the road, that can only be avoided by taking out the improperly installed component and installing a replacement component correctly.

Paul,
Well, to keep you going, I would suggest the soldered-on leads should be adequate to carry the current, and will be OK for a while. But some consideration should be given to providing a good heat conductor through the leads too. I believe the continuous leads would allow better heat dissipation from the resistor. If it were me, I would order a replacement, but you can use that one for now with no harm - the current drawn is not very high until you start testing the KPA100 at full output. 73, Don W3FPR > -----Original Message----- > > > Not fully reading the directions before installing the component, I > immediately clipped off (at the respective holes where the two > component leads were inserted) the leads after installing current > sensing resistor R7 into the closest of the 3 holes on the two solder > pads.
