hickok: Tube Tester; 600/533

I have a hickok 533, which is the same as the 600 except larger and older, which has test settings for the 205D, but in the roll chart it states, " Bayonet pin is over the grid pin. Use an adapter". Does this mean that the Plate and Grid are reversed, and therefore an adapter is necessary ?. Or is it just a warning to place the tube correctly in the four pin socket because, the locating pin is not placed in the same manner as most other tubes ?. As for the 102D I have no data for testing it. I have three testers, (1) Heathkit TT-1A, (2) Hickok 600A, (3) Hickok 533, so if anyone has testing information on these two tubes for any of my three testers, I would appreciate that help. Thanks in advance for any help with these questions. Jay |

Hello Jay, I dont know your tube testers, but you can test this tubes with the follwing settings: WE 205D, Triode, base same as 3B/151A (f, p, g, f) Filament: 4,5V and 1,6A Grid: -15V Plate: 250V Tube is good if plate current = 19mA and mutual conductance = 1,6mA/V WE 102D, Triode, base same as 205D (f, p, g, f) Filament: 2,1V and 1A Grid: -1,6V Plate: 130V Tube is good if plate current = 0,8mA and mutual conductance = 0,51mA/V Best regards, Hans-Thomas Schmidt |
