A few Clarinet questions:

1.   Should wires from the RCA jacks to the PCB be shielded? How about wires to volume controls and selector switches?
2.   Should the screws/nuts used to attach the PCB to the chassis be plastic?
3.   What is the source of the heat that the sinks are supposed to be dissipating?

Thanks

If you design using stock parts, then shielding should not be necessary.  It's all sort of built-in.  For example, several of the heat sinks are used as shields, not sinks.
