Estou revitalizando o meu ka4002, troquei os capacitores eletrolíticos e os transistores, menos os de saída.
minha dúvida é sobre os fios que saem do (s10) chave liga/desliga e vão ligados na placa principal me parece que nos pontos 52 e 53, estou enganado? Não liguei e funciona normalmente, qual seria a função, pois olhando para o esquemático não consigo entender esta ligação (ac para cc?), outra dúvida, me parece que o atenuador de graves atua muito pouco quase imperceptível, utilizando e entrada aux, seria isso mesmo?
agradeço se alguém do forum me passar conhecimento.
Forte abraço.

My kenwood ka4002 - help electrolytic capacitors and transistors, except for the output ones. My question is about the wires that come out of the (S10) on/off switch and are connected to the main board. It seems to me that they are at points 52 and 53. Am I mistaken? I didn't connect them and they work normally. What would be their function? I can't understand this connection (AC to DC?) when I look at the schematic. Another question is that the bass attenuator works very little, almost imperceptibly, using the aux input. Could that be true? I would appreciate it if someone from the forum could give me some information
