hola a todos en el foro. tengo una duda conceptual respecto a cómo consigue el voltaje de funcionamiento (vdd) el circuito integrado viper12a en una fuente conmutada, que según como lo veo en el diagrama, estaría viniendo del segundo bobinado...

hola, muy buenas tardes a toda la comunidad de yoreparo. mi consulta es sobre una lavadora lg carga superior modelo wfs2604ppk para 6 kg de ropa seca que no completa el proceso y se detiene después del lavado, esto es,...

Olá a todos os capatazes da YoReparo. Eu tenho esse rádio Philips 09RB098 Philips de onda média transistorizado e é difícil sintonizar as estações, emitindo um ruído alto com a interferência entre a estação e a estação. Uma vez sintonizado,...

Muito obrigado pela colaboração. Um esquema de um rádio semelhante me ajudaria a localizar onde está a bobina oscilante e o transistor responsável pela conversão de frequência, pois você também sugere que o oscilador local não funciona. Na ferrita existem...

Olá a todos. Eu consulto transistores para este rádio que atualmente captura apenas uma estação de onda média nos 900 kHz. Sob essa frequência, o rádio começa a emitir um tipo de pulsos rápidos e não mais estações podem ser...

Hello to all YoReparo foreros. I have this transistorized Philips medium-wave 09RB098 Philips radio and it is difficult to tune in to the stations, emitting a loud noise at interference between the station and the station. Once one is tuned,...

Thank you very much for your collaboration. A scheme of a similar radio would help me to locate where the oscillating coil and the transistor in charge of the frequency conversion are, since you also suggest that the local oscillator...

Hello everyone. I consult transistors for this radio that currently picks up only one medium-wave station in the 900 kHz. Under this frequency, the radio begins to emit a kind of rapid pulses and no more stations can be heard....

As I said in the other post, is this Philips radio model 09RB098 that you want to work at your discretion. I have changed several components with replacements from a radio that works well (electrolytic, the 2 transistors 2SA341, the...

Good evening, gentlemen of YoReparo. Earlier in a recent post they helped me with the calibration of this radio. Now I have the problem that its power is low, at maximum volume the sound of any station is heard only...

Hello, dear foremen of YoReparo, more than anything it is a conceptual doubt about what happens when replacing a voltage reducing resistor with a capacitor in the series feeding circuit of the valve filaments. The radio in question is a...
