@tubetime Huh? On a power supply board? What sub-circuit are these resistors part of?

@attilakinali there are 7 of them. they trim the output voltages and a few other parameters

@tubetime interesting. I would have thought that 1% resistors would do the job for the voltage feedback of something like a computer.

Any idea why they need this level of accuracy?

Tube🍂Time replied to Attila

@attilakinali 1% is indeed fine for this. but they probably thought doing it this way was some sort of competitive advantage lol

@tubetime I.e. they IBM'ed the shit out of this power supply 😆
