just tried them, cannot get the full output voltage How come? input is 10k, output is max 7,2k so there is a loss at putting !v in and getting 0.72V out. Anyone? See this thread:

So here's mine - sort of a badly needed panic volume control between my DAW and monitors. Parts are RS 100K stereo pot, 2 14.75K resistors (closest I had), 2 RS Mini-Jack connectors and courtesy of Hobby Lobby, a 50 cent box & a 99 cent knob. No silver wiring so I don't think I broke $10 on this project.

23 steps instead of 24. But how to calculate a 10k 23 step att.?

Quick question
I just built this setup using the 100K audio taper Alphas from Radio Shack with 22K resistors running in parallel. everything works great but I am not getting much in the way of volume... There is no sounds through he amp up until around 3/4 turn of the pot... Any ideas?
thanks.

Hi,
I talk to someone about my passive preamp and he starts talking about phase difference between frequency. I don't really understand. Is this a real problem or iit is just some electric concern?
I built my passive preamp based on this schema:

The preamp sit between monica (from diyparadise) (without the gain stage) and a gainclone
Thanks

Output impedance of my source is 75ohm, input impedance of my power amps is 100K. What Alps pot, 10K, 50K, 100K and wich resistor should i use? Thanks a lot!
Today i tried a 10k log alps with 10k resistor (shunt mode) sound is realy nice but almost no bass
Next experiment was a 10k linear alps in normal mode, no series resistor, know i have realy nice bass.
I am confused now what i should do. Come on guys lead me in the right direction.
