All controls (vol / / / etc) are via pushbuttons -
I'm looking to graft in a conventional rotary pot as a volume control

had a switch for the 12v dc to the MP3 module then that'd mean I only
needed one 'user-accessible' control.....

I'm pretty sure I have several old style twin potentiometers with
integral mains switches ex-equipment lurking in the "too good to throw
away" box - If you like I'll try and dig one out and if found you are
welcome to it.


Hi Peter
That's a very kind offer.
I'll see how it works out with the toggle-switch approach,
and if I hit a brick wall then I'll get back to you...

Many thanks
Adrian
