Technics amp su-v505 help volume control

I need a potentiometer, looks dual 100K B , What does mean B? It is linear or log? On the diagram VR 201-1 and VR 201-2. But only on Vr 201 -1 is showing value 100K (B). Is there any place to order even with small PCB? Any idea about substitution? Standard part - dual ( tandem)?
