First gen DX-7 issues

David
 

My old trusty DX-7 is showing signs of wear. I'm in need of new volume and data entry faders. Does anyone know of a source for those parts? The volume I can deal with using an external control, but the data entry fader is so bad and glitchy it's impossible to tune.

Hi Dave,

I uploaded a photoshopped picture to the photos area of the group detailing the engineering specs for these Panasonic EWANF style slide pots. The album name is DX7 and DX27 Volume and Data Pots. These are 10k ohm single pots and the volume is a log taper and the data is linear. Click on "original" to expand the drawing to full size to view all the details and dimensions.

Now for the bad news... I've never been able to find them as they are obsolete. If anyone knows of a source please (DX7 sound) chime in.

Hope this helps, Fran

P.S. I have seen where DX's were parted out on Ebay but there you're dealing with pot luck... They may be good or bad if you even find them at all. :-)

Oh, oh, one more thing...

Did you try spraying them with cleaner. I use Radio Shack's cleaner & lubricant spray to revive noisy pots. For $10 US it's the best deal I've found yet for restoring scratchy slide pots.
