[Elecraft] Head Phones and a note about Replacing the KI03 I/O

[Ron D'Eau Claire]

What mod/document are you referring to about Karl? 

If there's an error in one of the docs we want to fix it.

AFAIK, *all* mods are carefully tested including making the resistance
checks on an actual unit to ensure they are accurate before the document is
released.  

If it says "open circuit" the resistance should be many megohms. Sometimes
it's possible to "turn on" a junction somewhere in the circuit by connecting
the DMM leads in a certain way, but the correct reading should be obtained
by reversing the leads. When that's true, there should be a note in the
procedure to reverse the leads if the readings are wrong. 

Also, if an older ohmmeter is used, it will often produce totally different
readings because it applies higher voltages to the circuit. In fact, older
"ohmmeters" not specifically designed for solid state work can destroy
integrated circuits and transistors with the voltage some of them apply.

   First off I ran across some people taking about Head Phones and the  
K3. If I what use a Mono pair of phones, I like the Kenwood HS-5 8  
Ohms. They are well mad and sound good. But I regress, at the end of  
replace KI03, one is told to cut both traces on the RF board, from the  
bottom of the radio. They state if cut properly, you should read "0"  
ohms on your meter. Well, I got reads of between 12-14 ohms. Is there  
not all kinds of electric stuff on the other side of the board for the  
circuit to follow. My mag glass works just fine to show I cut the  
copper out the PC board. Just so you known
