Cassette recorder museum

Este ”casetofonul” militar (probabil primul din lume) american ce folosea casetele „magazine MX-303/ANQ-1 si VRW-1 (vezi alaturat); din spusele vanzatorilor americani, a rezultat ca s-a folosit pe bombardiere B-29 si de marina militara in al 2-lea razboi si a fost scos din uz prin 1949; litera "G" din simbolizare inseamna "ground" = aparatul era utilizat in baza terestra, cele din avion avand litera "A" = airborne, asa cum e scris si in interiorul casetei. constructia – specific militara – pune accentul pe calitatea materialelor + rezistenta la socuri: astfel, rezistentele sunt fixate prin infasurare pe cose si apoi lipite, 3 din cele 6 lampi sunt fixate pe pufere din cauciuc, tot ansamblul fiind fixat pe un sasiu/soclu tip sina, cu ajutorul a 4 picioare cu bucse metalice vulcanizate in pufere de cauciuc (a carui calitate/elasticitate s-a pastrat intacta !!). Motorul, f. mare, cu max 1725 rotatii/min, conceput a conduce role cu fir in greutate de cca. 0,4 kg si a lucra pana la temperatura de 40 gr. C. Lampile se aprind, motorul misca, dar casetele au firele incurcate si nu l-am putut proba. Greutatea e pe masura- cca 18 kg, iar dimensiunile (cu soclu) sunt 36 x 34 x 23 cm.

foarte rar, functional; cu schema.

It is an US military wire cartridge reproducer-recorder unit (probably the first in the world) which used the ”magazine MX-303 / ANQ-1" and also VRW-1 cart (see attached) ; it seems it was mounted on the B-29 bomber and also used by marine corps in the II-nd WW and was put out of use in ca. 1949; letter "G" from symbol means "ground" = it was made for terestrial base ; the item for plane was inscripted w. letter "A" = airborne; construction - specific military - emphasis on the quality of the materials + resistance to shocks: thus, the resistors are fastened by wrapping and then glued, 3 of the 6 lamps are fixed to the rubber bushings , the whole assembly being mounted on a chassis / socket base, with a 4-stem, rubber-coated metallic bushing (the quality /elasticity of which was kept intact!). The big and strong engine, with a maximum of 1725 rpm, conceived for to drive wire role with a weight of about 0.4 kg and a dust up to a temperature of 40 gr. C. The lamps are lighted, the engine is moving, but the cassettes have twisted wires and I could not prove it. The weight is about 18 kg and the dimensions (with the socket) are 36 x 34 x 23 cm.
extremely rare, working shape; w. electrical diagram (bought from Tony & Deborah Bowen, Anderson,SC,USA)
