Other manual shows 2K, but that beside the point.

This pot needs to dissipate quite a bit, huh.....3W dissipation will make it 5 to 7 W rated pot at least.

I was about to suggest trying to trick that thing: you can connect a large, say, 6-8W resistor of 2.1K in parallel to the ends of the pot (the circuit will see an equivalent of 1.72K) and try to regulate it this way, but I am not sure what the 10K pot's rated dissipation is - needs to dissipate 1/2 Watt, so needs to be 1-2W rated at least.

You can try.....
