I can't find 2 deck 2.5K rotary pots...
So i want to try some ssl9k preamps using a 2 way lorlin rotary switch connecting some resistors...

I really don't know how to calculate the resistors value to obtain something like a logaritmic rotary potentiometer.

Anyone can help me ?
 
Google stepped volume controls you should find what you need.
 
Look here

I would like to ask How do I connect this Pot to the board?

theres :
Gain A (2 holes)
Gain B (holes)
and there's 2 x 3 pins (Pot legs)
Wich goes where?

thanks

LOLOLOL

Thanks a Lot Marty,
I've read the SSL main thread so many times....

But it was a long time ago, when I was learning ou to solder.
Way before the almost finished project stage.

What resistors are those?
 
Great.

Thank you All.

This is a really simple project to do, But the errors in the pdf , the omissions and lack of a detailed document make it a bit trickier.

After I finish mine, I will do a new document for the project to share.
