[Elecraft] KPA100 and KAT100 in EC2 - is replacement of L1 on AUX2 necessary?

[Don Wilhelm]

Ken,

Although *supposedly* the inductor should be able to supply the needed 
current, I recommend replacing it with a toroid.
Especially if the inductor is of the older miniature type.
12 turns on a FT25-43 or FT37-43 core will work nicely.
