One thing that I can say folks is that I have a Moog 921 VCO sitting here
that went out for a makeover generally not working, and when it did, it
tracked "okay". It had 741 opamps in it.

When it came back... OH MY... Talk about stable, talk about clear, talk
about tracking... 20hz -> 60*KHZ* dead on.

The main difference? The Doctor had replaced all the 741's with LF411's.

I'm sold... My 2600 will be getting LF411's front to back. I'll let the
EE's figure out the slews and current sink and voltage diffs, but real
world proof did this decision for me. :)
