    Give it up now. The author wanted to make a "dangle" and he did. He is satisfied with the action, and that's what counts. Everything could be done better, but from what he wrote, he has no intention of doing a recording studio or broadcasting music over the air so fine scaling is not needed. This is my opinion and I agree with it completely.

    And that's it :)

    The LM358 is a dual operational amplifier. Why are there two tiles? Are these layouts based on the diagram from the first post? Unless I missed something and did not read what the other half of each bone is doing, I'm sorry.

    You had to make full use of one LM358 chip instead of two, only half of each. How can amplifiers be wasted like this? :D Everything would then fit nicely on one PCB.

    Hello

    I think that popular and cheap J-Fet amplifiers, for example from the TL08x series, could be used in this design.

    I am interested in the frequency response of the amplifier of these indicators. Make the popular audio sweep test 0 - 20kHz.
    The LM358 is rather poorly suited as an amplifier for drive indicators.
