Sure, I'm happy to provide specifics.
The tabs on the terminal strips for both the octal and the nine-pin required trimming, they wouldn't fit otherwise.
The screw holes on the chassis for both the octal and the nine-pin needed to be enlarged.
The finition of the chassis plate was overall poor.
I've since finished the build, and there's a background mid-level pitch that persists even when the volume's at zero. The first build was dead quiet.
This second build required more tweaking of basic components, and doesn't sound as good.
If that's trolling, call me Bert.
