[Elecraft] Re: Which Capacitor is it?

[Ted Turk]

Hi All,

My K2 will be in the post soon.  Meanwhile I have been avidly reading 
in readiness for the build.  One mention of this mod refers to C72, 
many others like Stan & Jim refer to C71.  Checking the schematic for 
the KPA100, C71 is listed as  0.0018uf  decoupling RFC3 to ground and 
C72 0.01uF decouples the gate of Q6 if I read it right.  Can someone 
please check this out before I need to get a solder sucker out!!

73 to all, thanks for the excellent reflector and those at Elecraft for 
the excellent manuals.  Looking forward to joining you with the build 
and on the air.
