STEREO CASSETTE DECK
1970 - 1980
Por mis manos pasaron muchos decks, pero ninguno como este, de una marca que no daba mucha confianza, pero increíblemente, con un cambio de cabezas de FF (ferrita) y unos cuantos ajustes, quedó 1A. Las grabaciones tenían una tremenda calidad en las altas frecuencias y en las bajas, era impresionante la compatibilidad que generaba con los otros decks, todo lo que se grababa en ese deck sonaba fenomenal, de una calidad tal que no se podía comparar con grabaciones echas en una Akai Gx-9, una Nakamichi Dragon o la RX 505.
Me ofrecieron mucha plata por él, pero solo lo vendí cuando me fui de Cuba. Siempre me he arrepentido de haberlo vendido, pues debí conservarlo como recuerdo por todo lo mencionado y además porque realmente fue mi primer deck de norma 42” que llegaba para quedarse.

Después llegaron otros decks; unos se quedaban por un tiempo y luego los vendía, convirtiéndose en un negocio de compra y venta. Normalmente me quedaba con cuatro para hacer duplicados y acelerar las grabaciones que me solicitaban, pero los remplazaba periódicamente por otros mejores.
Estas son las maquinas que pasaron por mis manos:

Otras máquinas que pude usar y comprobar su fama.
La Revox B 710 mkII formaba parte de los equipos del Teatro Nacional de Cuba. Cuando trabajaba allá, grabé algunos casetes para calibración, generando tonos desde la consola MCI JH-636 y grabaciones de cinta (Reel to Reel). Por ejemplo, el álbum Blood, Sweat & Tears, de la banda del mismo nombre, que tiene un sonido muy especial y una gran mezcla para comparar azimuth y respuestas de frecuencias.
