Dumb questions for smart people

1. What happens to a preamp, if the FET is not biased correctly? What kind of faults would a person be able to audibly hear?

2. I have an old Mic Preamp with badly torn traces on the PCB. Would it be ok to use thin wires to re-route the trace?

3. If my mic preamps power supply - toroidal transformer goes screwed am I? I hear they are custom made for each product, so buying off the shelf ones is nearly impossible.
