    A Few Questions Please

    Phase linear 300 resistor question

    Hello. I am about to replace resistors r101 and r111 on the driver boards of a phase linear model 300 but the manual doesn't say how many watts the resistors are. They are 3.3k ohms but other than that it says nothing. I discarded the old burnt resistors a long time ago so I have no way of...
