  • MODEL R-28 Revolutionizes RADIO! It's unbelievable--but true! The new R.C.A. Radio-easily the most amazing radio of modern times...will bring in American and Australian Stations WITHOUT AN INDOOR AERIAL!

    Offering tone, power, range, and selectivity positively eclipsing any other 5valve set, the R.C.A. Radio incorporates every known radio advancement, and equipped with the new 1933 valves, it gives a standard of performance hitherto unknown in New Zealand. You owe it to yourself to see and hear this super set before buying any other. 

    Who'd think so little could buy SO much! Compact enough to carry anywhere...light enough to balance in your hand...yet the new R.C.A, Radio is a full-fledged 5-valve superhet, equipped with tone control, dynamic speaker, and new R.C.A, 1933 valves, A demonstration will convince you of its worth, for another almost unbelievable feature of this set is the low price. £14/10/-

    1933 VALVES.. The R.C.A. incorporates the new 1933 Valves 2A5 and 2A7, specially designed and patented by R.C.A. Until you have heard the R.C.A., you have not heard RADIO, so vast is the difference they make to tone and volume.  

    Made in the USA
