[Elecraft] K2 parts identification/substitution

[smithyg2004-k2list at yahoo.co.uk]

For anyone searching the email list archives: Elecraft Support (who reply incredibly fast) have confirmed that both components are correct (gold-blue-gray-silver is correct for RFC6 and for Q6, 2SC5739 is a substitute for a 2SC2166.

  Hi.  My K2 RFC6 is gold-blue-gray-silver.  Is this correct?  I.e. all my other RFCs have the tolerance band *after* the three bands for the value whereas RFC6 has it *before" them.  Just another manufacturer's quirk?
   
  My K2 Q6 driver transistor is marked "C5739" which doesn't match the parts list (says it should be a 2SC2166).  Is this a substitute or an incorrect component?
   
  Many thanks,
  Graham G3ZOD.
