[Elecraft] K3 Board Re-seating Guidelines

[Don Wilhelm]

  John,

There is nothing specific to "re-seating".
If you use the existing board assembly steps in reverse, then put it 
back together again, you will have accomplished the "re-seating".

Normally, you do not have to re-seat all the connectors - just the ones 
involved in the problem, and it normally involves the DSP and Front 
Panel boards.  The replacement steps for the upgraded DSP board should 
have all the information needed to do that task.
