Mixer Pot Change

[AzzR]

Ok im building mixer number 3 found here http://www.all-electric.com/schematic/simp_mix.htm and i want to put in sliding potentiometers but i can only get 50k ones witout looking to hard, and all the pots on this project are 10k. If i use 50k pots what kind of resistor do i have in parallel with the pot  to get it down to 10k or can i just use the 50k and have a bigger range or will this be to big a range.

Thanks

Also is this mixer clean or will its clip at high volumes

you might have some problems but i imagine you already know that but heres a link that will give you a program that will help you figure out what you need to accomplish what your after without doubt.

Dreamseller, I'd just put the 50K pots in. I just had a look at the circuit (HEY! it's my old mate Batz!! in Adelaide) and, it won't make a noticeable difference. In fact probably better for guitar, if anything.

Cool thanks. Also what is the output on this thing going to be like. I asume I would be able to plug it into a guitar amp without much troubles but will it have enough output for a PC soundcard or will I need to build another preamp. If so which one is best for PC recording into a PC

Thanks

Gain will be unity.  If you want it to be higher make one of the feedback resistors higher in value (and adjust cap value to compensate for this change).  The resistor in the second amp would be the better choice to make bigger as the first amp is doing the lion's share of the work.

Shouldn't be any problem driving a PC soundcard.
