10 turn clarified 20K pot question.

[Low_Boy]

So instead of changing the clarified mod on a radio I have hear and because I never did a 10 turn clarified. Am I buying the right pot if I see 3 wire hookups. All listings are shown like this. But do have. 3 terminals Rotary Potentiometers Pot 10 Turn Variable Dial Resistor Wirewound. And I do know I need a 20K.

The ten-turn pot as a clarifier can get tedious without a turns-count dial on it. The exact resistance value may not be critical, since you'll probably connect the left end to ground and the right-hand end to the 8 Volt supply. May want to unhook some of the fixed resistors that serve to help center the factory control.

And the exact details differ from one circuit board type to the next.

I also noticed on the picture of the 10 turn the solder tabs are in a row. and one appears to be a copper color. I have not ordered a pot. yet but I imagine it would probably have some paperwork with it.

I'm used to seeing a schematic representation of the hookup printed or embossed into the housing. The assignment of the wiper lug is not necessarily the one in the center of the three.

Thanks Nomad I guess it is printed on the pot.

Yep, the wiper lug would be in the center of three if this were a conventional single-turn type. It's the bottom lug in this pic.

They also make it easy to understand. Sort of like the Common lug on a 3 way house switch. The common is a copper color and the other 2 screws are silver.
