Hi all-       Perhaps it is a linear taper.  During repair I measured the resistance change as I turned the control, and seem to remember it as acting like a log-taper pot.  Memories are a funny thing, though, and I'm probably wrong.  But, a linear-taper pot might be easier to find in an electronics shop parts bin.        Thanks-        Bruce D. --- On Thu, 9/25/08, jeffrey coulter <i_am_zontar@ yahoo.com> wrote: From: jeffrey coulter <i_am_zontar@ yahoo.com> Subject: Re: [newmellotrongroup] Re: New file uploaded to newmellotrongroup To: newmellotrongroup@ yahoogroups. com Date: Thursday, September 25, 2008, 3:49 PM --- On Thu, 9/25/08, john barrick <astroboy@cinci. rr.com> wrote: > From: john barrick <astroboy@cinci. rr.com> > Subject: Re: [newmellotrongroup] Re: New file uploaded to newmellotrongroup > To: newmellotrongroup@ yahoogroups. com > Date: Thursday, September 25, 2008, 5:36 PM > Hi Bruce.
