    Unequal heating elements in series - brain fog trying to work it out!

    *now* i understand - thanks!.....maybe an explanation ( i should have taken a couple of photos) the heating elements are thin film (x2) (originals 950x45mm by approx 1mm thick) sandwiched between an insulated outer shell and an inner plastic lining, the case being cylindrical lying horizontal...

    Unequal heating elements in series - brain fog trying to work it out!

    thanks for that - yes... its mechanical fit, the film (its similar to the heating film now used for underfloor heating - which is what i'm trying to use) or.... and sorry for another question, could i add a resistor to the original (115v 75w) element to bring that up to 220v and wire them in...

    Operating a DMX controller with a footpedal - help and guidance please !

    thanks for coming back - i've learnt something already ! - you mean that a voltage is continously (or rapidly) applied to the buttons and 'altered' when the button is pressed.... but no... no oscilloscope If what you are suggesting is right - is there a way round it? - roger
