If I have a 1meg/100k dual pot is it possible to add resistance to the 100k to make it 1meg and giving me a dual 1meg pot for my stereo
The quick answer to the OP's question is no. You can't just add a resistor.
The long answer is that it is sometimes possible to transplant a pot track from one housing to another. Only worth doing in exceptional circumstances, like reparing an obsolete component to get a rare item working again.

Dual pots with different resitances are not uncommon, they just won;t be found in applications like stereo volume or balance. Probably not a lot of applications in hifi circuits. WOuldn;t surprise me in a guitar amp or some sort of audio processing gear. For example one deck sets a level while the other deck controls a threshold in some compressor. That sort of thing
thanks for your replys. Found some dual pots though still looking for a dual pot with an AC on off swith
Hi, I was looking for volume pots/potentiometer of Alps 150k for my Sansui AU-519 amp. Its quite difficult to source this. I need it to replace the existing ones as I was told they are faulty. I have faced problems with the volume suddenly dipping very low and also with crackling sound too..also the relay (on/off switch) also keeps blinking alongwith the crackling sound and volume almost lost.
sajjuththomas... that could be more than just a problem with the pot. It may be nothing more than a poor or cracked solder joint which is really common on equipment of all ages.
Or the pot needing simple cleaning.
Most pots in commercial equipment are made to order. SOmething like a dual pot with on off switch is almost certain to be a custom item for some stereo manufacturer. SOmething like that in a catalog may well be surplus goods. However, that doesn;t stop you from looking for a "replacement" part from some other maker. I have a couple old Sherwood dual concentric pots, and they would work in something other than a Sherwood if I needed them to.
