I started to consider the two changes recently to my Legacy.  The
standby B&C was repaired last year after some windings failed.  Then
the primary failed and I found all the diodes failed and it was
obvious some of the diodes had failed long ago.   Now, I'm realizing
that my G430W radio static has completely cleared up whereas before it
was noisy and static ridden.  Also, the Avidyne display of erratic
EGTs is gone.   It just hit me that I've found the problem(s).
Something to keep in mind or check if similar issues develop.
