Cabinet, covering, grille and panels tell a separate story
Cabinets, coverings, grilles, handles, feet and panels can be restored independently from the circuit.
Look for added holes, inconsistent materials, reproduction panels, replaced logos and differences in wear. A new grille is not equivalent to replacing a transformer, but both should be disclosed.
When cosmetic restoration has been performed well, document which materials were original and which are new.
Separating cosmetics, structure and circuit makes the assessment much clearer.
