I wonder how it distributes clockwise which pin is the anode, which is the cathode, which pin is the filament. in the schematic diagram I know. I just can not get a valve and know who is who. Could you please help me? Thankful.
Each valve has a different pin distribution, as in the case of integrated circuits. This distribution should be consulted in the tube manuals according to the type. These manuals provide the characteristics of the valves and the corresponding arrangement of the pins. In our site in "World of tubes" you will have in the item 8 (Download), several manuals to download and to consult for free. You can also use the datasheet search on the home page for this.
