[sdiy] Dual Audio Filter

[Dave Brown]

I volunteer at the vintageTEK museum and recently saw a Krohn-Hite 3202
Filter in their museum store for sale.  It is a dual low pass/high pass
precision filter.  I took the top off to see their control setup which
consists of a shaft and gears to control four potentiometers for each of the
filters.  I just thought it was an interesting design so I put a picture of
it on the vintageTEK webstore.  Just click on the thumbnail to bring up a
larger photo.  Enjoy.

or  ...  go to   vintagetek.org/zencart   and select "Electronic Product"
and then "Misc Audio" from the menu on the left.
