    Unknown potentiometer

    Hi, I am restoring an old Proton P1100 preamplifier. It has a lot of issues but I am slowly getting it back to working condition. There seems to be an issue with the potmeter controlling the base, so I removed it and tried to clean it. While it got better it's still not working as intended...
