Can this be seen? & TL072's

[Tony Allgood]

>While I am at it, any thoughts about changing TL072's for
NE5532's in VCA's?


The 5532 is a power hungry chip, ie. quiscent current consumption is ten
times higher. It has better drive characteristics but will not sound
much better than your TL072 in your application. If you are using the
op-amp to buffer an OTA, use an 072 because of its higher input
impedance. I think the 5532 has a 100K input resistance, even when used
as a follower. No good for SVF, then. It also suffers from a very small
maximum differential input voltage, 0V6.
