Help with faulty mc202


I have a 202 with 2 issues I wanted to see if anyone could help with.

The first is that the sub oscillator works on. 1 octave but not on 2 and the bottom setting sounds the same as the first.

The 2nd Is the tempo knob doesn’t work (physically damaged), I believe it is a c category reverse log pot, 1M. I have managed to obtain a 1M log pot but it is an a category, can I Use this and do I need to wire it differently ?

Thanks in advance for any help on these matters
