    Hi, I’n new here.
    I have an old LPB-1 (small box without footswitch blue grafics). I was using it powered by my adapter. Accidentally moving it the red cable that connects the battery detached and don’t know where it was soldered. Can someone tell me where it should be soldered in the circuit or post a picture of the inside of a LPB-1?

    If the black cable is soldered to the pot, the red wire goes to the switch. If the black wire is on the switch, the red is soldered to the pot.

    The black cable is connected to the switch. Should I solder the red on the pot “back”?

    I have a question about powering th LPB-1. I tried powering it in daisy chain from my 1Spot power supply. But it didn’t work. Is it positive polarity? Can I change this?

    What transistor is used in your LPB-1?

    That’s not going to help. Open the unit and read the number on the transistor.
