What is this? - Page 2

What info do you need? Sure looks like a 3.3 watt 30 ohm to me, and most likely a wirewound.

make it 3W 330 ohm

I miss typed... it's 330 ohm, but you think I got it right? It was on a Pa amplifier pre-amp board and I am wanting to replace it. I just want to know what would be a good sub for it.

Just replace it with one of equal resistance and the same or greater power rating. I would recommend going one power rating higher (5w resistors are common and cheap) to guard against future problems.

Not sure why there is an automotive grade component in a preamp, though.

Thanks, I will use a 5 watt wire wound 330 ohm to replace it. As for why an automotive grade resistor was on an audio preamp..the preamp is over 20 years old. (Realistic MPA 100 model 32-2023) A lot of resistors on this amp look like automotive type.

This is the preamp board section. You can see signs of overheating around two resistors at top center of picture.
