National, Radio Portátil Modelo MR-5, 1970´s, Made in México (HECHO EN MÉXICO) by National Mexicana, S.A., Boulevard Toluca No. 22, Naucalpan de Juárez, Estado de México.
I found this receiver with its cardboard box, instruction and warranty policy, unfortunately the cardboard box is very battered and unpresentable, but I took pictures of some fragments that helped me to make a suitable frame for the AM receiver picture.
It works very well with its original electronic components. The chassis has a combination of silicon transistors (for the radio frequency and audio preamp stages) and germanium (for the audio amplification stages): BF494B, BF495C, 2 X BC558B, 2 X AC187, and AC188; powered by two "AA" size batteries.
National Mexicana, S.A., was founded in 1967 by Matsushita Electric of Japan and the mexican Grupo Industrial Guindi, locating the manufacturing plant in 22 Toluca Boulevard, Naucalpan de Juárez, Estado de Mexico. At the end 60´s and during 70´s National Mexicana, S.A., manufactured several models, from pocket to table top radios and some with turntable.
