Welcome to this website of old cathode ray tubes and related antique physics Instruments
On 37 pages you will find my historic tube collection and a lot of background information.
Enjoy a trip through time when most of our modern electronic techniques were invented.
This website shows you the complete cathode ray tube evolution of the past 150 years starting with the
Geissler tube with all it's spin-offs until the last produced modern CRT of this time.
