Hello all. I am having a really hard time identifying this resistor to replace in an amplifier. The amplifier is a Trace Elliot GP12 SMX. The back of the amp says 400W, 800W peak. The colors look to be brown red violet and silver to me. But I cannot tell. Some have told me that can't be right because the value is way too high. I will post pictures of it here.

The other thing is I have looked up the schematic for the amplifier and it says its a different code, but I see other obvious errors. Here is a Schematic that says it is for the Trace Elliot GP12 SMX 350-400W amp. It says the resistor would be 470k resistor. But it also looks like it says that both R24 and R23 are the same value, that is obviously not the case. Here is the link to the schematic:

I am looking for R25. The connector broke off of it and the dude soldered on a piece of metal to the short bit of metal left hoping to make the connection. I don't think it is working right. Which is why I want to replace because the amp is having problems. Want to make sure this is not the problem. Thanks for any help.

R23 and R24 ARE the same value...

They're just facing opposite ways around.

The schematic may say 470k (haven't double checked it yet) but that's not what's in there. I recon that's a 1k at the moment, although can't be sure without being able to see the first stripe. It's the only standard value resistor that will end in black red brown though.

The schem says that the busted resistor should be 4.7k, not 470k, R26 is a 470k.

From what I can tell the schematic is accurate so a 4.7k in there would work fine.

EDIT: that only affects your post eq DI out so unlikely to be your issue with the amp though
