Potentiometers
« on: July 30, 2006, 09:32:02 AM »
I am building the NPN boost with my dad as my first pedal project. I have all the parts for the project except for the potentiometer. The guy at Radioshack didn't grab it when he went through my list. So I have 2 500k pots sitting around. The project calls for 5k pots.

What would happen if I used a 500k pot in its place?

I can get the 5k pot but not right now.

It will not work

The 5k is a part of the design.  It works with the other resistors to set the operating point of the transistor.

is the 5K pot the only one that will work because i cant seem to find 1 anywhere  :icon_cry:

Many of the members here order from smallbearelec.com
Steve Daniels, the owner, is a great guy and stocks most of the parts you could ever need for stomps. Check out his site for 5k pots, pretty sure he's got them.

A 4.7K might be easier to find.

connect 6k8 resistor in parallel with 500k pot as a first aid measure.

What is the difference between 16mm pot and 24mm pot?

Those are the width of the pots.

So that means it doesnot matter which ever I get?

No it does not matter.
The smaller ones can be easier to mount if you have a small enclosure or you have lots of them in the same box.

xcuse me for splitting this one hair:
16mm & 24mm are the radii of the knobs. actual pot casing dimensions matter inside the box.

i'm sure you understood each other, but, just in case.  ::) to myself.

I prefer 16mm because they are smaller and take up less room inside the enclosure, especially if you are using several pots.

I used 10K pot is my NPN Boost cause I didn't have 5K and they worked.
