Hi Whoops

I'm Ipin, I just finished installing 2 channels of the 9k, except the gain switch.
Do "stepped gain" that you posted work?
And is it going to work with 2 separate rotary switches? I can't find the double deck one here.
And also is the closer value of the resistors also working? again, I can't find the exact value. Do they really effect the Pre?
 
Thank you very much

Why do ask that? would I or anyone have any interest in posting info that doesn't work?

If you are doing this project you need to read this thread first a lot of helpful info

Hi,
I really don't know what you mean by "2 separate rotary switches", can you explain better?

You need one switch that has dual gangs/decks as far as I remember, if you don't find it we can help you sourcing that out.
If you use a POT it's also a dual gang pot

Just post the original specs for the switch that are somewhere in this thread, as I dont have that info present at the moment

Hi Whoops
Yer, instead of 1 dual decks switch can I use 2 single deck rotary switches? So it will be like turning them together (complicated isn't it haha)

Thank you

That seems a bit absurd so I can't reply to that.
