Hi Tom, Volhout, All,

I can confirm that the Dual pot (at least the ones I have) are indeed 'Internally' wired as per the diagram above, Further to that the taper is Linear as at the half way point I get 10k from Pin 1-2 (and 2-5) and Pin 1-3 (and 3-4).

If you remember Tom I mentioned that the Pot seemed to work in reverse, Fully anti clockwise was full volume and vice-versa. However as it is a wheel sticking partially overhanging the PCB it `also' makes sense as UP is louder and DOWN is lower.

IMHO, the pot does quite a good job and is easy to adjust to your desired level.

My speakers like the ones you bought Tom arrived today and they are marginally softer than the old transistor radio one I used, however they are still reasonably loud and when put in the sandwich of 2 PCB it will probably make a bit of an echo chamber.

Kind Regards,

Mick
