| Cool, thanks for the help, I thought I was going crazy. Could not find it. I guess I'll have to bring in in for servicing. |

| I just had a good look through the schematic I have and I cannot find R182,R183 either. Drawing number 990-227-00 Rev C. The version I repaired must have been different. I don't remember where they were on the board, it was a while ago. Sorry I can't be more help. |

Hi,
Thanks for that info. I searched through the service manual, and there was no listing for those 2 parts in the part listing. I have the original 450, maybe I'm looking at the wrong manual? Thanks again for your help! Pete |

Hi,
I also have the Mackie SRM 450 and am trying to replace the R282 and R283 10 Ohm resistors. I'm trying to do a DIY repair on the unit, but I'm having a problem locating exactly where the resistors are. Could you point me in the right direction?
Many thanks in advance!
Pete |

Hiya
Just repaired a Mackie SRM450 with thermal and signal indicators always on. R282 and R283 10 Ohms 0.5 Watt metal oxide resistors were open circuit. I replaced them and powered up with a Variac while checking Voltage drop across them did not stray too high, should be around 1 Volt. It's a fix. |
