Help! i have an old Cenco Geiger counter which had a Raytheon CK1021 tube inside a protective metal shield on the end of a cable that plugged into two different
machines to count the pulses put out by the tube. (one clicked and the
other used lignts to show accumulated total count.
I dropped the probe the other day and the tube now makes strange
rattles and does not work.
Does anyone know a source to just replace the tube? this tube is black
and about the size of a test tube with three pins in the base and a pointed
end on top that looks like where it was sealed when made.
any leads would be appreciated.
