<DIV><FONT face=Arial size=2>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.</FONT></DIV>

face=Arial size=2>(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).</FONT></FONT></FONT><FONT face=Arial size=2></FONT></DIV>

<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Finally got around to desoldering the 6
nasty pots on my OB-8.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The markings on the pots are what looks like a
"dp" symbol, followed by B5K and the number 477036.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV></BLOCKQUOTE></BODY></HTML>
