I see the merit of mounting the resistor with good clearance (on standoffs) outside of the chassis based on heat dissipation reasons, but I am at a loss understanding how the unevenly heated chassis contributes to distorsion...

Certainly, any AC circuit is better kept away (cleared, shielded, etc.) from any other circuit, especially signal carrying ones. I see the merit in doing this. Particularly when common mode rejection is small or zero.

I would appreciate if other inmates with similar experiences would pitch in and explain, especially the heated chassis and distorsion part...

Thanks,
Radu.
