Hello Pandu,
Ik had a BX760 once, which is almost identical to the BX765. I sold the radio for exactly the same reason. At higher volume the sound was superb and oké, at normal volume it sound's like a small transistor unit.
I know the volumepotentiometers are sometimes a weak point. You can check them with a analogue multimeter on a high ohm range, to see if the resistance value variates smoothly when turning the axle. Also the black capacitors often need to be replaced, because when they get moisty, they start to behave like a high ohm resistor.
That's not wat you want. In this case i would give all capacitors in the LF part a thourough check. I assume you have already checked the most important DC values (and currents), in the LF part of the radio?
Good luck,
Regards,
Nico den Haak.
