>dumb-ass who needed to remind himself that ground was the negative of the 9V battery
well that takes a load of my mind!
>nope, the LM386 is designed specifically for single-ended applications
oh lawdy! I thought to myself that an OPamp circuit would generate less noise, but with the circuitry I'd need for the negative voltage (it will be driven by 9V supply). I will remember this!
>that's 1000uF to you, mister.
sorry, I'm a physics student so I'm used to that. I will stop posthaste!
> they filter any transients on the power supply, and create a low-impedance path for AC signals to ground.
Got it, that's very practical and good to know! I remember having read something about using a lot of different capacitances across a circuit, when using a cap to isolate or stabilize, to get a low impedance over a higher bandwidth...

> practice of refering to transistors and transformers as 'trannies'
people actually do that? This makes me sad...
>you can prolly skimp on the 1000µf if your power isnt retardedly bad.
Ah, it's fine, I got three of them for 900000µ€ in a sale at a local store. Also, power will prolly be retardedly bad, since it'll be a birthdaypresent for a pal of mine who plays guitar and his supply is cheapo crap, so yeah...

Anyways, thanks a lot for the help, fellow /diy/nosaurs! I appreciate it! As a thanks, here are dancing birds!

THANK YOU!
exactly what I meant by just answering stupid questions as well. Here is a gif of dancing birds for being a cool guy fo you.
