Lee DeForest may have invented the vacuum tube but unlike him, you can actually explain how it works! Well done Don!

[@AllAmericanFiveRadio]

Thanks and your welcome.

Rick, I really enjoyed your educational presentation and the experimental tube you shared is very cool. Best, Don

[@AllAmericanFiveRadio]

Thanks, and your welcome.

[@skycarl]

Rick, you must have a small museum hid somewhere with all the cool stuff you show us. That triode tube is really something.
Great info my friend, thanks for sharing.

[@AllAmericanFiveRadio]

Thanks Carl. I hope everything is going well with you'll.

[@greggsvintageworkshop8974]

Very good explanation sir, and what a very special tube you have. Museum piece quality.

thank you , and your welcome.

[@midmodaudio6576]

Great video

[@AllAmericanFiveRadio]

Thank you!

[@kgsalvage6306]

Very nice old tube you have there. Is the tube still operating?

[@AllAmericanFiveRadio]

Yes the filament is good.
Thanks, and your welcome.

[@Gaark]

It amazes me that the tube is (practically) a century old, and looks perfectly useable :)
Do they always invert the signal?

[@AllAmericanFiveRadio]

Yes. A single stage Vacuum Tube output at the plate or Transistor output at the collector, will have a 180 degree phase shift between the input and output.

I'm looking at a 12AX7 datasheet with nine pins. What is the distinction between "cathode" & "heater" pins? Which one of these pins represents the "filament"?

[@AllAmericanFiveRadio]

The first triodes have a filament, control grid, and a plate. The filament is heated so that it can emit electrons. The control grid controls the electron flow between the filament and the positive plate. The more negative the control grid the less electron flow.
The triodes with a cathode. Now the filament is just a heater. The heater heats the cathode so it can emit electrons. The control grid and the positive plate functions as before.

triode like a 27 valve

[@AllAmericanFiveRadio]

Yes it is. Thanks
