[Elecraft] kpa100 toroid changes

[John Cooper]

Over the years the type of toroids in the kpa100 have changed.  Is this because of availability or other reasons?  I have a prewound set of toroids for the kpa100 but its old enough to not have rfc1.  Plus the the ones I have don’t match descriptions from the latest manual Im working off of.  I don’t have the originals either since I never ordered the kit.  Can I modify the L18 I don’t need anymore to work in rfc1 spot?
