Potentiometers - USA

Brit01 · 6th August 2009, 04:54 PM

I have a colleague visiting from USA and am looking for some good volume pots.

Possibly ALPS.

Or something similar. BUT I don't really want to spend more than 10/15 USD on each one.

Any recommendations for suppliers in USA?

Cheers

Mouser sells the Alps RK27, around $12 I think.

Thks. 11.71 USD

What's the RK097?

Brit01 · 6th August 2009, 06:31 PM

guys, there are 3 types of RK27 also.:

Snap-In Potentiometers 2-GANG 100K AUDIO

Potentiometers Flat 20mm 100k

Potentiometers Slotted 20mm 100k

What is the difference here?

Look at the datasheet (there is a link on Mouser)

One has a slotted shaft (for a knob or to use a screwdriver for turning)

There other has a flat on the shaft to aid in keeping the knob from rotating independently of the shaft when the knob is fastened with a setscrew or a knob with a D-shaped hole.

Question regarding a 10K alps I already have.

Lats night I put it into one of my linestage/headphone amps.

I'm getting huge amounts of noise when I go anywhere near the metal volume knob and hell breaks loose when I touch it.

Do I need to ground the outer casing or what am I doing wrong?

I have the third prong attached to the star grounding system.

Just read that I should try connecting the inground connector to the outside casing.

I'll try this when I get home.

update:

Yes it was the unearthed casing on the alps. I connected a wire from the screw to the ground and made it dead silent
