KPA100 Component Installation Gaff? Acceptable Correction?

[Paul Clay]

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.

Thanks,
Paul, N6LQ

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.
