Hello Colleagues !!! This radio that I show you is from a relative, he has too much affection for him since he belonged to his mother, I would like you to help me with some circuit, data, the data sheet has a circuit but I don't know if it will be the same. The integrated one is the CXA1691BA: Overview of the platelet from the component side: I know that the topic can be quite comprehensive, but I would greatly appreciate every help, every contribution, since it is something of great sentimental value. I can remove components, circuit on a sheet, take values from them and check them (except the one that is like a transparent square that has to adjust several things, but with your help I will check as you tell me). Greetings and thanks a lot! from Buenos Aires, Argentina.
