Can I swap a Stepped Attenuator for a Potentiomer?

Hi I have a Motif MC-7 Preamp that I am going to hotrod a little bit. I wasnt thinking of it and dont want to but when you turn the volume control fast it makes a painful squeaking, I dont turn it fast but its not a good sign and cleaning did not address it as its in a sealed case (Very nice pot that I cant find)

Also there is some crosstalk between inputs on the selector switches. DACT Makes a unit that looks like it should fir the bill more than fine. I was thinking of using either Goldpoint or DACT stepped attenuators if possible or using as good if not a better potentiometer.

What hurts is its completely dual mono meaning to volume controls and 2 input switchers.

Ok, So I Did a lot of searching and as long as you have the same impedance/resistance? you should be good to go?

Rather amazing to think a machine could go 100% all the time that wasnt origanially designed this way, Is this right?

Also what are the best Stepped attenuators, DACT, Goldpoint, Khozmo or Elma or someone I havent heard of?

Thanks yall, I really appreciate it. My preamp uses awesome older ALPS Pots. They are encased in a plastic/resin? compound. I am really interested in what I will see in my upgrade especially as it is already two mono preamps.

I really appreciate all the help and now look forward to more homework.

Does anyone know the advantages of going with a higher quality input selector? I am having crosstalk between my inputs and I dont really care but I am sure it has to at least somewhat affect my preamps ability to achieve it full potential
