[Elecraft] K3 Power Reading/SWR/ALC Problem

[Paul Christensen]

I have a K3 at a remote site about an hour north of my home so
unfortunately, I cannot quickly investigate an issue that's recently
developed.  After reviewing the K3 schematics, the root cause is likely
isolated to the following parts on the PA board: D36, D37 (BAS70 - Schottky
directional coupler sampling diodes), and/or U16 (LM358 dual op-amp used as
a voltage-follower).  

My question:  are these three parts leaded or SMT/SMD?  Perhaps I'm not
looking hard enough on the Elecraft website but I don't see a detailed
B.O.M. for the K3/K3s.  I want to be ready for replacement without wasting a
two-hour trip to/from the site.  Thanks.
