hanzooo Posted September 18, 2011 Report Posted September 18, 2011 Hi, Sorry i speak little english, i have a Class-D MMATS 3500.1 amplifier, i tested the value of résistors, R174 is 40 ohms and R175 is 45 ohms but R176 and R177 is broken (R174 to R177 is similar). You can help me to know the values of these résistors ? My link 1 My link 2 My link 3 Thanks
STEvil Posted September 19, 2011 Report Posted September 19, 2011 should be the same parts as 174 and 175 if you can get the numbers off them. You cant measure them while in a circuit btw. They have to be removed from the board to be measured properly.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.
hanzooo Posted September 20, 2011 Author Report Posted September 20, 2011 Hi R174 and R175 is not the real value, i see one number on the R174, only 3, it's 3.3 ohms or 33 ohms and not 330 ohms because it's too high. Thanks
