Hi,
I'm working on a Solid State audio amp and want to know if I'm checking the +B and -B voltages correctly with my multimeter. What I have here are both of these voltages outputting from a bridge rectifier and I'm putting my positive probe on +B and the negative on -B, which results in FAR off tolerance voltages considering the amp still functions (with a couple intermittent issues). Since B- is a negative voltage (opposite of the B+ voltage), am I supposed to treat it as an independent voltage and ground to the chassis/common instead when checking either +B or -B? I just want to be sure.
Thanks
