that diode may be just for safety

Might be a voltage doubler from the look of the diodes?

in case someone plugs in a musical instrument adapter

And TIP122 with the zener as a reference for a cheapo linreg maybe

Too tired to trace that out

why are these traces so BIG

THICC traces save lives

big voltage fam

ya

b-but my amps

you want
1) thick traces
2) clearance

it just looks like thick traces

clearance is not so

THICC traces for THICC amps

Prolly was just cheap to make with through-hole parts

with this much wasted space you would think the clearences would be at least 1mm

they can afford to space things out

its about 0.6mm

v2 🤢

5v 1a into chink power supply - LED lit, so far so good <:alismirk:230784726615588865>

it sounds worse

:(

it doesnt say which side of the barrel is positive or negative, I assume the inside is positive

that's often the case

older music keyboards n shit had it reversed for god knows what reason

i mean the reason is there as was explained by Dave from EEVBlog some time ago

but it still fucks with people's heads

its quieter with the makeshift phantom power

magic

well, it wasnt the polarities

i have a huge 18V 6A power brick laying around but im not sure if i want to die just yet

i'll just have to make due with my motherboard for now

i'm not even sure how phantom power works

It trickles a bias into the balanced audio lines to power the mic electronics

Which is decoupled from the output audio
