Default Logarithmic Pot. instead of linear?

Hello,

I am new here and this forum is incredible.


I have a very old pioneer amplifier and i want to change the volume and balance pots.
My problem is that the volume pot is a dual linear with loudness control at 100KB and cannot find to buy a new one.

My question is:
Can I use dual logarithmic 100KA with loudness control pot instead of the dual linear 100KB pot?
For the balance what pot should i use linear or logarithmic?

Thanks a lot for your help.

I'm not sure I understand you correctly?

You cannot replace a linear pot with a logarithmic one without changing the surrounding electronics in your amp - double logarithmic ain't no fun

Balance is usually a linear pot.

Have fun, Hannes

some balance pots have zero resistance in the track over half the sweep range.

My amplifier is a Pioneer SA-720 and the volume potentiometer writes 100KB(1). I was wondering if you can tell which one i should use (linear or logarithmic)?
