Why so many resistors?

  1. Apr 27, 2017 #1
    Hello. I wonder if I can take some of these resistors off and make the signal stronger without breaking the rest of the components. Is this possible?

    Also why are the non-trimming capacitors needed?

    I have a picture attached.

    Thank you!

    Each one of those resistors is doing a job. Do you know why they are there? You could in principle redesign the function so it doesn't need as many resistors, but given that schematic, they are there for a reason.

    Would you ask if you could take off some of the tires of a car and still drive without breaking the rest of the components?

    Reminds me of one of my favorite quotes from the movie Amadeus.

    The first transistor and associated resistors make up the pre-amp, so if you decide to pound the microphone with sufficiently high volume, you can try omitting Q1 and it's bias resistances.
