[Elecraft] K2 Assembly problems/Info 080 Message

[Don Wilhelm]

Tom,

Did you remove the Front Panel board and the Control Board before making 
those resistance measurements.  Those resistances are for the board 
alone after its assembly.  When plugged into the RF board, the 
measurements can be different.

Does U1 still get hot?
