Rega Brio resistor question
one channel of my Rega Brio stopped working so i opened the case and found some obviously burned out resistors, 2 labelled R19 and 2 labelled R54. i am a total newbie (but can solder) so i'm wondering how i know how many ohms each of those are so i can replace them?

is it the case that all R19 and all R54 resistors on the same board will be the same? i attached a picture, i tried to figure out what they were but can't for the life of me!

Hola Neilll...

Usually resistors die a painfull death because something else died before,
usually a transistor ... that being said a schematic is in order and maybe a wide shot of the offending(offended) resistors and associated stuff....

Those resistors look OK, no discolouring. The blackening looks to have come from something just off photo (near red wire)
Which Brio model do you have?

Do you have a Multimeter (DMM) to measure and prove your suspicions about the resistors? There's not a lot to be gained by guesswork and appearances even with the best schematics and advice in the business.

The resistor values are shown by colour coded bands and there are plenty of charts with explanations to read the values on the web. Here's one to get started with: Electronic color code - Wikipedia, the free encyclopedia
The resistors in your pic. are 5-band coded and don't read quite the same as more common 4 band types.

the resistors in the pic i posted are not the burnt ones, they are examples of other good onces on the same board that are also labelled R19 and R54. since they're 5 banded i'm having trouble figuring out the resistance of them

Try this neillll. It lets you put your colours in and gives the value,
Resistor color code calculator - 3, 4 and 5 band resistors

The bad news as others have hinted... there's probably more amiss than just some low wattage resistors.
