    Hi

    I am building a basic amplifier project for school and am having trouble with the preamp especially connecting a 2 pole 3 way switch on my pcb. My teacher has given me a schematic but I am not sure still..... Can anyone help ??? Circuit is attached.

    Thanks in advance

    The input selector switch needs to be a rotary type switch. Take a look at an E-Switch part #KC26A30.001NLS. That is in Digi-Key as part # EG1954 @ $6.90. That is 2 pole 6 position.

    After re-reading your original post I think you were asking how to wire it. Here's a hybrid pictorial for you.
