[Elecraft] K2 , Control diodes

[Ken Chandler]

I have just got my K2/100 and installing the various elements etc. There are 2 diodes D1 & D2, page 15, D1 is situated at the left top corner. Now I take it the black end is the cathode!! but which way should it orientate on the board!! On the outline for the diodes on the board, there are 2 internal marks, one is vertical line, the other is a sort of half circle..ish.

I hope this is a good enough explanations!!

Thanks
