Telecolor 5603

The Telecolor 5603 is a colour television set of Romanian design made by Electronica in Bucharest, the second series after the Telecolor 5601 [1]. Its electronic channel switch was redesigned with Microelectronica MMP710/MMP711 circuits, the colour decoder used A 3510D (PAL) and A 3520D (SECAM) circuits, and the video module a single A 3501D video processor [1]. After 1990 its chassis was adapted for the Top Color 5101 [1].

In 1988 Electronica launched the first colour television set of its own design, made possible by the experience gained with the imported sets and by Romanian components: line transformers from IEI, delay lines from Electro Argeș, programmers from Conect, ferrites from Urziceni and active components from IPRS [1]. It was designed by Mihai Gănescu with a team; its vertical chassis was largely similar to that of the Cromatic, with a Romanian MOSFET channel selector and a redesigned programmer and colour decoder [1]. The sets had headphone and tape sockets and audio-video connections for a video recorder, and drew at most 110 VA [1]. Two series were made, the Telecolor 5601/5602 and the Telecolor 5603, which differed in the programmer, decoder and video module [1].
