|from Radiomuseum.org||Model: L-1 De Luxe - Lafayette Radio & TV Corp; New|
|Shape||Chassis only or for «building in»|
|Dimensions (WHD)||17.125 x 9 x 12.125 inch / 435 x 229 x 308 mm|
|Notes||The chassis L-1 for 105-120 volts and L-2 for 220-240 volts 40 cycles or 110 volts 25 cycles share the same schematic - and also L-3 Regent and L-4 Regent are listed on that Rider's schematic 5-9. But the same schematic/chassis is also used for the models L-5 Viceroy, L-6 Viceroy and - displayed on page 137 of the catalog - the models with Capehart record changer as L-7 and L-8 and with Capehart two-speed phonograph L-9, L-10. The higher number in a name pair is the higher voltage. The given voltages for L-2 in the catalog page 12 are not repeated for other models but 220-240 volts 25 - 40 cycles. Both can be true.
It is a chassis for two electro dynamic loudspeakers and there is the note "Dual Twin Voice dynamic speakers". One speaker is pitched for high notes and the second for low notes, which arrangement results in an overall fidelity of practically 100% within the extremes of 70 to 4500 cycles. The models have a tube 57 as noise suppression for silent tuning and semi class "B" push-pull output with two tubes 46. The models feature Automatic interference suppression, manual interference control, automatic volume control, triple dial tuning, improved twin voice dynamic speakers, tone control and an illuminated tuning meter. Sensitivity is less than 1 microvolt per meter, selectivity for 10 kc separation. It delivers potentially 18 watts but this has been reduced to a max. of 10 watts. Current consumption is 110 watts. Rubber cushion mounted tuning condenser. Four chokes for the elimination of hum and distortion. Illuminated full vision tuning. But broadcast band (BC) only!

In this catalog page we discuss also the origin of Lafayette in respect of the first radio dealing or manufacturing company to use this name. Gulbransen division Wells-Gardner was manufacturing this chassis - also for others like Montgomery Ward and Radiolek (SR230).
