I'm restoring a vintage Astor radiogram.The volume pot is unique in that it is 250k ohms dual gang with 2 x 25k ohm tags so I cant just buy another one? The front channel of the pot measures 166k ohms in circuit and the back channel 183k ohms,one channel works OK but the other is playing the radio at approx half volume at fully anticlockwise position? The only way to control that ''bad'' channel is to use the balance pot,it acts as a volume pot? Is there someway to fix this, maybe by putting resistors in series in the circuit or by somehow fixing 25k ohm tags to another 250k ohm volume pot?
