Making a vacuum tube self-made Movie released with ambient music plays back

Vacuum tubeIs an electronic component that performs signal amplification, detection, rectification, etc. with an electrode enclosed in a glass or metal tube whose inside is evacuated. Until a transistor appears, it is a vacuum tube which was a flower form of an electronic circuit, but in recent years an active place has decreased sharply and it has become a degree to sometimes see with some high end audio and guitar amp. The movie "Hand Made Vacuum Tubes by Claude Paillard" released at Vimeo introduces the atmospheric atmosphere with a feeling of handmade such a vacuum tube.

Hand Made Vacuum Tubes by Claude Paillard

Some of the vacuum tube's retro feeling shape should be enjoyable just by looking at it.


First of all, pulling a scissors of a Tokutoku knife ......


We cut the very thinly stretched metal plate.


Fold it delicately with pliers ... ...


Bend in a tubular shape and weld with both ends pinched.


At that time, a single metal rod was attached together.


Next, prepare the wire with a certain length ... ...


I will roll around with Kurukuri.


The coil was completed.


Next, attach a thin wire to a slightly thick metal rod ......


Make a part of the electrode.


Next we will make "tube" of vacuum tube.


Blast glass tube rotating with burner ... ...


I will bend the end of the tube little by little.


It became the shape like the trumpet ahead.


Wrap a heating wire around a glass tube and cut it by applying heat ... ...


I will wipe the glass tube again.


Squeeze the upper part of the softened glass tube ...


Molding to a flat shape.


Next, combine thin wires ......


I inserted it in a deformed glass tube.


Sandwiching the glass tube and the wire ......


Cover the protruding wire at the top with a thin metal plate and blow it with a burner.


When it cooled down over time, it became like this form. The road to the vacuum tube still seems to be long.


Apart from the earlier parts, I will rewind the rotated glass tube.


As I continue to focus on one place intensively, I will indent the dense places.


The glass tube which has been kept fogged becomes soft and gradually thin like a crow ... ...


It became a closed tube on one side.


Break the previous part and sprinkle it.


Rotate the glass tube with its tip flattened, and burn it with a burner.


When I keep patiently strongly pushing, the tip gradually gets rolled ... ...


It became like a hole opened at the tip of the light bulb.


While holding the hole with a burner, bring a thin glass tube close ... ...


Both will stick together where soft becomes hand.


If the joint is blown again with a burner ......


The glass tube stuck snugly. This will eventually be used as a pipe to drain the internal air.


Welding the coil to the part which combined the glass tube and the wire earlier.


It became such a part.


Furthermore, when a circular metal is stuck on the coil ......


The lower half of the vacuum tube is completed.


Soak the finished parts in chemicals.


And finally we will combine parts and glass tubes.


It is no longer a familiar burner, it is integrated, and the upper and lower are united.


Place the finished tube in a special machine ......


Close the lid.


Switch on. The inside is almost vacuum state.


This is almost a completed vacuum tube.


On the cover of the vacuum tube ......


Insert the electrode.


A vacuum tube is completed by sticking a vacuum tube and a cover.


I will light the vacuum tube which is completed immediately.


It is also possible to make a vacuum tube radio.


It was a self-made tube made by a vacuum tube that seemed to be enjoyable just by looking at it.
