A significant number of our accelerators use old style Allen Bradley 2W carbon resistors like these:




The accelerator supplier, IBA, can no longer supply them. They have an alternative but do not recommend mixing old and new due to different aging characteristics.


Does anyone know of a supplier of these resistors, generally in the meg ohm range? I would only be looking for small numbers to repair damaged strings like above.


Anecdotally there was a previous problem with this type of resistor where the manufacturing process was changed so that the internal end of the leads was cut to a chisel point which resulted in them exploding when a high voltage was applied.


Best regards
