386 substitute?

[DWBH]

So I know the 386 is a low voltage power amp, also used in many distortion pedals.
Can a single opamp be used to substitute it? Or is there any way to substitute the 386 with opamps?

[Mark Hammer]

Power amps are made to be able to feed lots of current to low-impedance loads.  While the internal structure is different, some op-amps, like the NE5534/32 and the LM833/837 are also intended to be able to drive low-impedance loads.  Whether or not they can "substitute" would depend on the specifics of the circuit.

But i general, no, there are no simple plug-in replacements from the op-amp universe.
