Question about Audio Players & Recorders
The speaker hums when power is applied (no audio input). The only info I can provided is from the top of the transformer. PT005V076UA Ferderal B3-033-2-76-F Built in Thermal Fuse. A search on the internet was unfruitful. The manufacturer could not provide any assistance.
The transformer is fine its the amplifer probably has dried up electrolytic capacitors usually a speaker has one capacitor to rework the audio levels and emphasis for the tweater
it wont be the transformer/speaker for sure
and for sure its the amp
try another amplifier or replace your ones capacitors

Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.

It turns out its most likely one of the resistors on the PCB on the amplifier plate.
My uncle has had the same problem and managed to replace the resistor and its working as normal now.

make sure you have the speaker connection right if you do then it is a ground problem try plugging it in a different outlet

Check the circiut board for any blown capacitors. Sometimes it's that simple as replacing a capacitor. But then again, what is causing the capacitor to blow??/ Hope this helps.
