[Elecraft] HiCur after KPA100 mod

[W3FPR - Don Wilhelm]

Gregg,

The capacitors are not the problem - never were, that was a premature
conclusion (the cap change seemed to work at first).  The real problem is
that the manufacturer changed the 1.6 ohm 2 watt resistors to an inductive
design and did not notify Elecraft.

Give Scott a call or email support at elecraft.com to request 2 replacement
resistors.  You can likely leave the 5600 pf capacitors in place with no
problem, or you can change them back to the 4700 pf value if you prefer.

73,
Don W3FPR
