Windmill bass knob

[Cvp1969]

bass knob on Windmill doesn’t really work. If the gain and treble are down below noon, then I start to hear the change. I double checked the whole PCB and triple checked the components around the bass knob. Everything seems ok. I can see is that when I check the the pots on the circuit- the bass pot (a500k) it reads 15k.

May be worth trying a linear pot. Probably not going to hear much difference until you get past noon on the bass pot unless you are down tuned.
