Stereo Attenuator Options

Stereo Attenuator Options

2002-02-20 by gbeaugard

Would anyone care to suggest a "MOTM quality" stereo pot for a custom 
module?  Should be sealed, conductive plastic, audio log, long life, 
etc.  I'm having trouble finding these in small quantity for less 
than $35 ea (ALPS blue case).  Sorry if this has been covered, I'm 
new.

Thanks
Grant

I have often wondered the same myself, and wondered about pots with
switches.  I found some that I was planning to order from Mouser to see if
they might be worth having.  They are on my next pending order to Mouser.

On page 282 of the new catalog, there are pots under the brand name PIHER.
They are solder lug instead of PCB mount.  Most of the trimmers are carbon.
But, at the bottom of the page, they show the PC16 series that are described
as "sealed" and "plastic."  There is no mention of "carbon" in the
description.  They are available as single gang, single gang with switch,
and dual ganged as stock part numbers  from 1K to 500K in value.  Single
prices just under $3 each.  sine I have not tried them yet, I cannot report
on their suitability.  But, it sure looks better than open carbon.  It
appears from the illustrations that they have long shafts that might require
cutting to length.

The only thing that does not seem to meet your criteria is the taper, these
are linear.  But, if you get the big one you can simulate something close to
a log taper (now where is that document?).

I'm gonna order a handful just to play with.  the description also says "up
to 4 gangs and a switch on a common shaft by special order."  I bet there
are some significant quantity minimums for something like that.

Anyone have any experience with these?

Noble makes a nice one for $20.00. Available in 10k to 250k Log from
Michael Percy Audio Ordering Information . Page 14. ($25 minimum order).
I have used these with good success. The footprint is smaller than the
Alps so it will take up less space behind a modular panel. I have
wondered about those Piher pots from Mouser as well, let us know Larry.
