[Elecraft] Re: Additional info - Problems = Alignment Part III K2 #4993

Check T4 Gary says... gotta have the correct number of windings.. ok I check
it, double check it. and check it again... the correct number of
windings....all is ok... oops!!!!!! holes 1 and 2 should be green windings
and 3 and 4 should be white, just like I wrote in the book to make sure....
well, guess what, I had them reversed... after a little struggle to take out
T4 and put it in correctly.... everything is fine now.. (at least the
current part is ok)  ..It remains to be seen what else I might have done...
:)

thanks for all the suggestions... T4 and that area was the area most folks
pointed to..
