[Elecraft] K2 - Transformer T4 upside down

[Don Wilhelm]

Euan,

Wires 1 and 2 are on the same winding, and 3 and 4 are the other 
winding, and it is symmetrical about the axis that tuns through the 
center of the core.  In other words, if you flip it over in that manner, 
it looks the same - no need to change it.

Now if you had turned it around the other way and soldered the 1-2 
winding in the 3-4 holes, that would make a huge difference, and would 
need to be corrected.
