Vector 4 Manuals

The Vector 4 in my colletion doesn't quite work - it squeals loudly when turned on. I'll get to diagnosing the problem someday.

Squealing is probably normal -- I have a 3 year old computer that squeals and every part inside it is fine.

The squealing sounds like a power supply problem. Maybe a bad voltage regulator or cap(s)...
