Laboratório 153 - “Kit para Estudos de um TUNER AM & FM POLYVOX - Parte 01”

Hello my friends. Some time ago, we did a complete repair and restoration of a Polyvox TP-300 tuner. During the restoration, we acquired a scrap tuner of the same type. Since we used almost nothing from this "scrap" and initially almost everything was working, we decided to assemble this study kit. The idea is to use it to show the step-by-step operation, component by component, of this equipment that had a very popular and widely used technology at the time, in this and other equipment, such as the CA3089, CA3189 and CA1310 ICs. Let's check it out??? All the theory and studies will be available throughout this series. Subscribe and like so we can continue with the channel. Click the bell to receive our notifications.
