Yes I am dealing with the version with output self-bias reistor 2.2K (which is at this point 3.8K and needs to get replaced), and 8uF which is nowhere to be found, and the resistor in question is a ceramic bobbin with wire wound around it (which at closer look is a cord with fine spiral wire around it, and then wound around the bobbin, I was wondering myself at first how 20 turns could produce 10K until I looked in a magnifying glass) and a sliding clamp contact.
