[sdiy] LM324 question

[Jim Patchell]

    The LM324 can be used just like any other opamp.  You can connect pin 4
to +15 and pin 11 to -15.  HOWEVER....I would not use the LM324 in any kind
of audio application.  Use a TL074 (same pinout).  If you insist on using
the LM324, you will need to add a resistor from the output of each opamp
(1,7,8,14) of about 10K to V- to bias the output stage to run class A.  The
LM324 has a class B output, and will give you one nasty crossover glitch.
