[Elecraft] K60XV

[John Wiener]

I continue to be baffled by my K60XV problem.  I have replaced R1 and  
C12.  I continue to get a short (zero ohms) between pins 13 and 14 on  
U1.  I thought I found a problem on the RF board: the coax shield may  
have shorted the lead from P1 lead 7 to ground...I insulated the coax  
shield exposed with tape.  My thought was to recommend that shrink  
tubing be used over the exposed shield on this side of the  
coax...similar to that used on the other side of the coax to the RF  
board.   However, I still get the short between pins 13 and 14 of U1  
on the K60XV without plugging it into the K2.

Can this be explained by a defective Z1?  Any other ideas?  Let's  
face it, there aren't too many components on this small board!  It's  
very frustrating.
