I have recently acquired this American-made radio, which looks to be mid-1930s. It has ten valves, most of which are clustered around a bizarre ‘tube island’. Not much is known about the New York based Luxor Radio Mfg. Co., nor whether they had any connection to the Swedish radio company Luxor AB, founded in Motala in 1923, or to production of radios in New Zealand under the Luxor name. Can anyone help? Does anyone know of another Luxor T100A, anywhere? Thanks, Lawrence —    |

looks like a unique and possibly rare radio you have there? with an unusual mounting for the valves. good luck with finding some info on it. Its obviously made for an export market, but 220 AC volts? I wonder what country?

I wonder what country? Thanks, Richard. I have posted details on the big Antique Radios forum and so far it has had more than 770 views, but it is still a mystery and no-one has admitted to owning another one. Some contributors have suggested that the New York-based Luxor Radio Mfg Co may have concentrated on exports, which might account for its very low profile in the US. I’m still not clear about the links, if any, between this company, the Swedish Luxor AB, and production of Luxor models in NZ. I intend to post on an Australian forum to see if there are any surviving over there. In the meantime, I am holding off on any restoration work. The cabinet is currently in a freezer. If it is unique, then the best I can do is a clean and polish. The auctioneers’ description said that the valves light up. Don’t you just love auctioneers? |

I'd be a little concerned with the filament voltages, running it on 240V when its stated as 220V operation? they might be a few volts higher than they're suppose to be, your filaments might not last the distance?

Hi Richard
240 Volts is only 9% higher than 220 Volts. 9% higher heater voltage. Based on the reasonable assumption that the valves have 6.3 Volt heaters (based on the metal octal valves fitted) the heater voltage will be about 6.9 Volts. I can't see that running them on 9% higher heater voltage will cause much of a detrimental effect on their life. The great thing is the valves should be really easy to find. I think I would be more concerned as to the mains frequency that the radio was designed to work on. If the power transformer was designed to run on 60Hz, then running it on 50Hz could overheat the transformer. To be fair, a search of the current world mains voltages & frequencies suggests that (most) countries that currently use 220 Volts mains run it at 50Hz. I'm not sure how 'safe' it would be to assume that it was like that in the 1930's as well?
