potentiometer resistance?

[Kamranbites]

My speaker volume control board, all potentiometer are old and wants replacement but I don't know the value of them,and doesn't it really matter to match potentiometer or i can just bring some and solder it ? 

Attached some pics of them

You have to get exact replacements. The range and type have to match, or else your controls won't work right.

If they're scratchy, they're probably just dirty. Get some DeOxit FaderLube into them and turn them back and forth across their entire range a few times. That should get them working properly again. (Don't use regular DeOxit or alcohol. FaderLube leaves a lubricant behind that you want in potentiometers and audio faders.)

Ok can I clean it will water? Then dry it nicely like 2 or 3 days in sun

I wouldn’t, especially if it’s regular tap water. Alcohol would be better than that. 

 

Spraying cleaner into the pot is already the cheesy shortcut way to do it. The best way is to take it apart and clean it with swabs, then add non-conductive grease dnd reassemble.

Should be written on them what they are. You can also use a multimeter and measure the resistance between the 2 ends (after desoldering it from the board). Also might want to measure end to middle over the range just in case they're logarithmic pots.

i use this to clean all my electric components including pots...it drys fast and leaves no residue

How do I measure them like one pod is 3 pin and other pods are 6 pins.

6 pin ones are likely 2 channels, the outer pins are probably one track, the middle ones the other, and the 2 center pins the wipers given construction considerations.

Outer pins ? The circuled one is were my 6 pin pod is soldered.
