Is there a low noise (not necessarily audiophile quality) OEM
amplifier that can be used to power an electret microphone for
connecting to powered computer speakers? Are there other solutions
for a microphone to powered computer speakers? It will be on 24/7,
so I would rather not use a battery in the microphone element.

Are there many low or medium quality USB microphones for
connecting to a PC? At first research, I have found few, mostly
those bundled with webcams and headsets. Maybe I need better
keywords.

Thank you.

FWIW. I have been all thumbs trying to use LM... amplifiers in the
past, and would rather use a preassembled amplifier.

If you want to take another gentle swing at building something, Jameco
has several audio kits that might meet your requirements.

They also have stupidly long URLs, so you might need to search thre
directly for audio kits.

Are you constrained to electret? You can get a dynamic mic from RS that
could plug right into the speaker plug, with an adapter made from RS jacks.

Is this for just making your voice louder?

Good Luck!
Rich
