[Elecraft] K2 D36

[KBG Luxford]

Hi Everyone,
I have restarted work on my K2 S/N 3068 after experiencing trouble 
aligning the VCO.  So I downloaded a fresh copy of the manual and have 
checked off the parts on the RF board up to Alignment and Test Part II. 
  Now I am puzzled.  The new manual mentions D36, a 5082-3081 diode, yet 
on the board, soldered there a couple of years ago (hence my memory is 
not clear) looks to be a 1N400x.  I have searched the Builder Alerts, 
yet there is no mention of D36.  Has there been a change to the 
specification of D36?

Many thanks
Kevin
