Default Orion 1200D

Does anyone know the value of theese ??

Im guessing they are a 3.3K resistor ..

Just wondering if thats correct Since they got hot and faded the color bands a lil..

They are measuring 2.766K out of the board So im just gonna replace them

Hi,
Check them with am ohmeter. You have 4 the same value. All 4 can not be bad.

Hi,
Sometime to get a good reading you need to lift one of the leg from the circuit.

Hi,
Also do not forget to check the power transistors. You may have a shorted
transistor to blown 4 resistors or heated them up.

They all measure the same as the first driverboard If you look at the backside of both driverboards thoose resistors got so hot they unsolderd themselfs from the board and made the driverboard black where they sit
