Dunno, haven't looked outside lately

10:05pm actually. Just spent 15 minutes rummaging around
in Philips new data sheet site

http://www.philipslogic.com/datasheets/

I've got an oscillator circuit that I used for a guitar tremolo. It
took some playing around with to get it very slow, I'll dig it
out later. It used a couple 0.47uF capacitors and a 741 which
drives an MC3340 voltage controlled amp. The problem I found
with those low frequency ones using op amps and capacitors
is that the sine wave wasn't always very symmetrical. Even a
chip like the 8038 has a lumpy sine wave at LF
