Subject: Cathode ray tubes for demos

Post:

Friends,

I have a set of very old cathode ray tubes with a ZnS screen to
"recreate" various experiments regarding Thompson and the discovery of the
electron. I am looking for a possible supplier in the event one breaks.
Does anyone have an idea for a supplier? I have not found one in my
standard catalogs....

Thanks,
Paul
