F5 bias
 
what the F..k. i noticed someting strange here.
my F5 bias is little over 1.7A. wich is spot on. but the transformer temp is way lower now, then it was before. what the ....???
the transformer temp is down about 10C. and the winding vibration is also way lower. i know the windings kan tight'n iaftr some time. but will that effect the transformer temp that much???
the primary/ sec voltage is the same. as is the bias and offsett.

EDIT: correction. the sec voltage is up .5V. but mains are at the same.

nobody?
i have seen this the other way. the windings get looser and temp rise.
but heck. this change after 4mnd.
