Welcome to the Photo Section of my Web Site. Select a manufacturer/catagory from the menu to the left to view thumbnails of the tubes. All thumbnails are clickable for larger/multiple images and additional information. After viewing the larger image use your browser back button to return to the thumbnail page. The dates given are the year of introduction of the particular tube type shown. In some cases the date given is my best estimate.
To see a listing of all tubes on this site check the Master Index.
The tube shown on the opening page is a Schickerling Z50 neon gas rectifier, running at 50 Ma plate current.
