This can be serious as the sub woofer driver or the feed circuit is faulty.
Unless the unit is taken out which is important the circuits cannot be traced. Try to disconnect the input and confirm the output or the line of signal path must be traced using a audio till the suspected noise producing section is isolated.

I purchased a JBL PB12 (120v) subwoofer from a friend. It worked excellent for a month or so, but completely went on the fritz yesterday. Whenever I turn it on, I get a loud whining noise, that starts high...


It sounds like something on your main board of your amp is going out. It is most likely the finals, or as you said a capacitor. Test the port with another speaker, if al is well then the wooferis bad. if not you will have to go inside the amp for repair. Depending on the brand it can be a little complicated. Try and narror it down to the proper componet, post back the results and we will go from there. Also is this sound comming from all channels or just the woofer?

CRT color moitor


The "terrable loud high pitch sound" could be the horz. oscillator.
The voltages off the crt should be (+) (-) 11v to 15v DC. Too much on Blue & Red guns will cut them off
