[sdiy] Oberheim OB-8

[doof]

You know doof, these pots are extremely hard to come by.  Not only is the spacing of solder pins not found on any currently manufactured pots, but the shaft-length is also an odd size.  A few hours of research and you'll come to the same conclusion.

Your best bet is to squirt some radio shack model #: 64-4315 (which simultaneously cleans + lubricates) into the convenient shaft opening and work the wiper over the wafer repeatedly.  Yep, the pot doesn't even need to be disassembled as the wiper assembly is clearly visible through a small opening. Just solder those old suckers right back on.  For future reference: don't desolder if there's an easier solution.  The OB-8 pots can be cleaned simply by removing both pot pcbs (held in place by about 12 hex nuts).


{all of which I did. Now there's not a snap, crackle or pop on tweakage of the former problem pots.  Miracle juice.}

  Hi all,

  Finally got around to desoldering the 6 nasty pots on my OB-8.

  The markings on the pots are what looks like a "dp" symbol, followed by B5K and the number 477036.

  Anyone know what kind of pots these are?  They look kind of like cheap alpha pots, but the solder pins are spaced side-middle-side rather than 3 in the middle.
