Hi everyone.
I would like to build a 12-stepped attenuator as my volume
control. But i'm having some problems getting the right values
for the resistors. I'm using the 1% resistors, and i want my
attenuator to be 25K.

Can anyone out there help me with the right values??
I want the switching to be as smooth as possible, meaning
the volume will increase and decrease nicely like a pot.

Thanks.

What will this be used with? 12 steps isnt enough for smooth attentuation unless you dont mind the limited max or minimum volume.

hi dokebi,

well, its for my head amp actually. I know 12 stepped isnt good
to make it smooth. But this is what i can afford at the moment.
Here are my values:
91R
220R
560R
620R
1K
3K3
5K1
6K8
3K
3K
1K
1K

The sum should be around 25 K.

jeez guys

I spent a lot of time setting up the DIY links resource

does anyone use it ?

there are many online calculators and links.I'm off to work so no time to post them but if needed will do so after work
