Question compressor Faiirchild 670 DIY

I am building a compressor Fairchild 670. I have a doubt, what hope someone of you can clarify.On schematic the r115 double potentiometer ( first channel ) and r215 (second channel)-value 100 K LIN-, seems supplied with a kind of physiological terminal for section. A link is placed between the two terminals. What is it? What type of potentiometer does using suit? What happens if is used a simple double potentiometer ?

Regards,
