Dont have a microscope, but nothing happened to it that I know of. It never got taken out of the arm and the thing was packed bomb proof and rode in my car with me, not the truck.
From looking at it with a magnifying glass, it looks just like it always did.
The left side is a bit better than the right, but it makes the Tabs sound like they are blown.
Inputs on the pre are fine...tested it with my old technics I used for 78's.
?? I dunno. ??
If someone has ideas??.let me know.??
