Highlights
Why this object
still matters.
The National T-66 is an early 1960s portable multiband receiver built by Matsushita Electric in Japan, housed in a textured grey vinyl cabinet with polished chrome accents. Its front fascia incorporates an ivory-toned slatted loudspeaker grille, an illuminated analog tuning and battery meter, and dedicated bass and treble tone knobs. Operating across standard medium wave and three shortwave bands, it utilizes a dual-concentric main and bandspread tuning knob for precise frequency selection.

Dial Engineering
Precision Bandspread Mechanics
Visible in the primary face photograph, the dual-concentric dial mechanism separated broad frequency traversal from minute shortwave adjustments. This mechanical reduction allowed global listeners to isolate distant international broadcast signals on crowded high-frequency bands.
Industrial Design
Portable Mid-Century Architecture
Seen in the lateral profile photograph, the cabinet balances functional portability with desktop stability. The slim profile integrates a textured vinyl wrap and a rear metal prop, allowing easy transport and angled tabletop operation during extended listening.

Condition
Honest wear,
documented clearly.
The radio displays authentic cosmetic wear consistent with age, notably two vertical strips of aged yellowish tape adhesive residue across the left section of the clear dial face. The polished chrome trim along the outer bezel and top carrying handle exhibits moderate surface pitting, oxidation, and scattered patina. The slatted front grille and dial surface show generalized surface dust and light discolouration, while the side covering remains structurally sound.
