Since its really tough to get a replacement with a loudness tap where I live (like an original pot), I decided to open up the volume potentiometer and see what can be done.
I opened the back of the potentiometer and started with the right channel.
What is usual in many pots - Three ends of a single wiper (which slide on the track)
RIGHT channel pot
The wiper end has
three slider like ends which rub on the surface of the carbon track. I lifted
two of them upwards away from the carbon track
. The third one I decided to shift its position. So using a thin needle I carefully shifted it towards the near end on the carbon track. I tested it after a couple of adjustments . I shifted the inner most slider of the wiper end towards the outer near end of the carbon track surface (where the slider/wiper has never rubbed on before). The other two sliders are just bent upwards away from the carbon track (no contact on the carbon).
NOTE - All of the above work was first done on the R channel carbon track
When the potentiometer/ volume/ wiper/slider is kept at minimum level, the wiper tip (the single slider tip whichis the end of the wiper i altered) touches the leg which is soldered to the Vol assembly board at the beginning of the carbon track. (which I never planned for) and the sound cuts of to ZERO.
LEFT channel pot
I did the same for the L channel. Then I closed up the volume control, soldered it back to the Volume assembly board and it works.
There is just a slight imbalance between the L channel and R channel when you increase the volume initially but then immediately as u go on increasing the volume to a moderate level the L and R channel balances perfectly and then all the way to the highest level the L and R channel balance is fair.
The results ? Well so far I am satisfied. I have managed to cut of the volume to actually no sound when its kept at ZERO on the control.
I am still testing it. Here is a pic of the slider ends of the wiper of the R channel
