  • Notes
  • There is a "Zetavox table model A.G." (AG) and a Zetavox console as "5-Valve Walnut Radiogram A.G." (Cat. No. R188/46408 for £ 33.12.0) plus one console with an automatic record changer, "5-valve Walnut Radiogram A.G.A. (AGA, Cat. No. R189/64608 for £ 47.5.0) with the same chassis and cabinet as the Radiogram console AG.

    We believe they have the same radio chassis and therefore we copy from the ad for the consoles: Three tuned TRF circuits, single knob tuning, completely shielded chassis with 2 variable-mu screen grid, 1 detector screen grid, 1 pentode output and 1 rectifier. Moving-coil mains energised speaker. Illuminated station dial calibrated in meters. Self-healing electrolytic condensers. Wave lengths 200 to 550 m (printing error is 250) and 1000 to 2000 meters. Mains transformer tappings for 200 / 250 AC, 40 to 60 cycles.
