members,

I recently worked with a fella who produced out of a bag a variable resistor tool

in short it was used for replacing/tricking thermistors on AC systems.

he said after he found it in my pocket they were available on line, OK please give a clue where................................................................................

I have looked at making one as parts could be sourced from maplin RS ect but this box of tricks was just right for the job, croc clips/prongs and a twist selector for ohms

any clues on where to get one?
