[Elecraft] K2 SSB Problem

[M L Hooper]

I just finished constructing the KSB2 Adapter and have installed the unit and am at the alignment stage (P-19 of the manual).  

The Course Carrier Balance Adjustment went fine.  

When I plug in the microphone and try the fine Carrier Balance Adjustment the unit begins to transmit at full output (10W plus) and continues to do so until I unkey the mic.  It makes no difference if the power is set to minimum instead of 5W or whether LSB or USB. 

Any suggestions will be appreciated.
