Hi everyone, i'm working on a synth-keyboard M-Audio Prokeys88SX, The volume pot is broke. The company is not having the part anymore. So Here i am, with the need for a slide potentiometer made by Alpha Part number B20KX2. The total lenght of it is 45 mm. The travel of knob lenght is 37 mm. There is 6 pins 3 on left 3 on right not shown on the picture(Through Hole Pins) The height of it is appx 6mm. The widht of it is 5 mm. Pictures are include here: thanks for helping me.

 

I forgot to say, come with a dust protection in it, if possible.

 

Frank Dude,

Welcome.

Have you moved the slide and checked if pot still works?

If you can not find a replacement, maybe it can be repaired.

 

Mouser stocks Alpha in depth. Also Bourns Pro-Audio stuff. Download the passives section of their catalog here (36MB) and look on pp. 944 or search on the first link for travel, taper and value. Yours is probably a B audio taper. You can measure it to be sure by removing the metal case exposing the carbon element. Measure the resistance from end to end to get the pot's value then from one end to the middle (touch the probe to the carbon). If it reads about 90% OR 10% of the total, its a B taper. If it reads about 50%, its linear.

Good luck.

EDIT: It also might be an OEM from these cats - Alpha US, different from Taiwan Alpha at Mouser.

 

well nothing matches, thank you anyway, the closet I have found is this one http://www.ebay.com/itm/Alpha-45mm-...382?pt=LH_DefaultDomain_0&hash=item3ce197bbd6

 

It looks like you have not bent the tabs back to open the pot. Why don't you do that? The pot is not usable as is, so why not open it and see if it is repairable?

 

I found these 2.
