Am perex® tubes are

Am perex® tubes are making music in the world's finest §F R ® systems .. . AMPEREX `preferred' tube types have proven themselves in the world's finest monophonic amplifiers. Now AMPEREX is paving the way with tubes for the world's finest Stereophonic systems. Developed in the research laboratories of Philips of the Netherlands, and applications- engineered by Amperex for the American electronics industry, these ultra- advanced tubes have proven their reliability and unique design advantages in late model amplifiers and tuners of the world's leading high fidelity manufacturers. Sold by franchised dealers everywhere... available for off -the -shelf deliveries in any quantity.
