Hi,
This is the thermistor that was shipped with Ormerods - [
uk.farnell.com]]
The cable should be two core with a cross section greater to or equal to 1.32mm^2. Often HiFi loud speaker cable works well.
If you have any trouble getting hold of the bits you need, let me know as we still supply parts for Ormerod.
Best wishes
Sally
