IG00152 versus IG00159 ...?
2010-11-11 by Quazimodo
Hi guys, Was wondering - if you drop an IG00152 into the place for an IG00159 - would it (the vca) still work? (ie use the filter envelope chip in place of the vca envelope chip - they are identical apart from pin14 not being used in the 159 I know it wouldn't work the other way around, as the 152 has the extra function - but looking at the schematic got me thinking. If so, and I am correct, why did they make the 159? They could have just made 152's and used them in both places..!? Cheers, TOM
