Hey folks -
I've been dabbling with some DIY audio schematics, and managed to cobble together the LM386 Little Gem amp, and I'm onto my next project.
I've got a KA4558 op-amp chip handy. All the schematics I've seen show similar op-amp chips used in pre-amp circuits, and not in actual amplifier circuits.
Can the KA4558 or similar op-amp chips be used to make a small practice amp, or are they only useful in the pre-amp circuits?
And yes, I know that if op-amps can be used for the pre-amp, the pre-amp circuit can be coupled with a power-amp circuit, which is a sideways way of answering my question. But that's not what I'm asking. I want to know if an op-amp can be used to build a small stand-alone practice amp, or if I need to also build the power-amp side to make it function properly.
