[Elecraft] PRE/ATT selection problems - K2

[David Walker]

Hi,

I have a gradually worsening problem on my K2 when I try to select 
PREamp,  ATT, or normal.  The symptoms are the relay clicks (normally) 
but on the PRE-ON and ATT positions I get attenuation levels on RX.  In 
Normal mode I get a very deaf K2.  Sometimes the only fix is to 
repeatedly press the PRE button until things return to normal, or I 
change bands and return to the band I was operating.

I suspect a dud relay.  My schematics packed away somewhere.  Could 
someone advise which one (or ones) would be the culprit.
