Hi All,
I’ve been lurking here for a while and from reading through the posts, decided to try my hand at fixing an old stereo. I picked up a MCS 3233 that has no sound from the left channel. I have ordered the service manual from onlinemanuals.com and took a shot at replacing some of the burned out resistors. So before I even started, I must have done something on the right channel of the main amp board because a resistor is burning every time I power it on. I replaced the resistor, and all the other ones that were suspect, and it still burns up. I can’t even check to see if the left channel if working.
Anyway, my question is this: in the service manual, it has boxes with voltage listed and it says “values indicated are dc voltages between the chassis and electrical part”. Do I measure with the power on, power off, plugged in, or unplugged? I know it sound like a ridiculous question, but when I measured with the power on none of the voltages were even close (before I jacked up the right channel).
Appreciate any advice.
Thanks,
Jamie
