This ain't an audio tube, but I need some help to translate the data on the tube package, as it's somewhat unclear to me as to whether this is a plain-Jane geiger tube or a boron-lined proportional neutron counter. What does the package say? If anyone has any info on the exact tube type, that would be appreciated, as all my web searches have been fruitless. Manufacturer?
