Thermal light on very low sound?
Well , have you checked that it's screwed on tightly , and no other gear is burned, especially your transformer and rectifier or a simple diode. With these things it's not u a huge search way , since it often comes out that your main power supply is broken, even it gives the right output voltages without a load. THE SAME COUNTS FOR OLD CAPACITORS WHEN YOU MEASURE THE WITH A NORMAL LCR METRE, until the load comes on it andvthe speed and capacitance drops like a two sizes two large, frozen underwear....
jHavebyou ever opend one? , you need often to cut a tight wrap, so have a sharp cutter at hand and to avoid damage to the outside of your unit, tape it with papertape, and not the gray strong tape .
Unwrap the cables , since theyre often wrapped, to your speakerunit and see what's happening and feel what's getting that hot. But first a look at the unit, since it also can be one capacitor is blown.... take a good look.I searched and searched and after days i say two burned black tiny caps.......
