GENERAL ELECTRIC
Mod. 429

Produced in 1955-56, this little device owes her appeal to beautiful lines and affordable cost.
It was manufactured in white, maroon, and dark red.
The years 1950-1960 were magic years for American Industrial designers.
Like many American devices designed and manufactured 60 years ago, the lines and style are still modern and undated.
In fact, the graceful lines and small size are perfectly suitable for modern settings.
This strong aesthetic personality is the main reason I restore this series of American production equipment.
There are modern appliances that copy or are inspired by these designs, but owning an original is another thing!

The sound performance of these radios are modest compared to the German giants on this website, but you can connect a digital source to this small GE radio.
This possibility will be discussed later in detail.
In addition to listening to your IPad or PC, this unit is able to receive a Medium Waves.
This device is powered by 120 volts supplied by an adapter to be connected directly to the local power supply.
It also comes with a connection cable with a 3.5 mm mini jack compatible with any modern equipment such as an IPod, PC, etc.

Founded in 1890 by Thomas Alva Edison the Edison General Electric Company invented and produced almost everything that has to do with electricity, lighting, household appliances, industrial products, medical equipment and more.
Here is a brief list of the major inventions of the company.

1895 World's largest electric locomotives
1896 X-ray machine
1902 The electric fan
1910 The first Hotpoint
1914 World's largest electrical installation The Panama Canal
1918 Generator for Niagra Falls - Enormous power of one of the great natural wonders of the world
1922 Radio station WGY
1927 Brings TV into the home
1930 First Electric washing machine

Following results of the researchs are less made public.
This company had no difficulty producing radio equipments!

Fonte - General Electric

But I confess that the real reason why when I saw this particular device was impressed and decided to restore it was this unmistakable resemblance.
I doubt that there is an Italian (over 50) who do not understand what I'm talking about.
Without using euphemisms ... for me it was a sinking heart!

Well-Lighted Tuning Indicator

Several American radios of this era used this solution aesthetically very attractive , rather than illuminating the entire scale is illuminated only the tuning indicator.
Besides being very pretty this solution lets you know at a glance, even from a distance, on which station you are tuned; In fact, after a while it is natural to store the different position of the light in the scale.
Beautiful.

AERIAL

This device uses a loaded antenna on the rear panel.
It's sufficiently efficient but extremely directive, so the position of the radio impact on the quality of reception.
The back panel is prepared to connect an external antenna.
In this case the reception would be perfect.

TUNING LIGHT

 

In this picture you see the mechanism that controls the movement of the light bulb.

I modified the original support, old and cracked at risk of a short circuit with a new and better support.

CONTROL PANEL

Dictated by a healthy American pragmatism controls are really reduced to the essentials.
Two knobs, one on the left controls the volume, the right knob controls the tuning.
The volume control should be used in this way:
- With a central setting of the radio is off
- Turning it to the right the device turns on and acts on the volume of the radio section
- Rotating it left the device turns on and acts on the volume Phono Input
Wanting to use the phono input you have to take care to tune to a frequency where there are no stations to avoid background noise.

LOUDSPEAKER

It was used an 8 inch loudspeaker performant enough despite its size.
The audio spectrum, which can be expected for transmissions in medium wave is sufficiently reproduced.

We are not talking of course of deep bass and treble bright, but only a voice clear and intelligible without fatigue.

RESTORATION WORKS

Originally, the GE 429 had the case in fair condition.
The transparent parts were a little dulled and crawl.
Originally was without the light bulb and his support. The connecting cables to the bulb had been isolated.
The tuning knobs and volume were moving together.
The radio section was not working.

Before restoration electronic.
The capacitors are all broken.
Even the electrolyte has been deformed by the spring support.
It would have been very dangerous to turn on the unit under these conditions.

The end of the electronic restoration.
Now you can turn on and make the necessary repairs and subsequent calibrations.
First tests.
Just the low frequency section works.
The first medium frequency transformer is broken, highlighted in red.
Highlighted in yellow the new bulb and the new holder in his support.
The windings seems good so it is one of the resonance capacitors.
The problem is that these capacitors are not outside, but inside the socket of the transformer.
In fact in the dielectric of the capacitors is deposited a bit of metallic material that connects the two surfaces.
Restored the dielectric must reassemble the capacitors.
Attention should placing the arms in opposite side.

It 'very important at the end of reassembly fold inwards the tabs with the welds.

The squareness of the coils will be assured support during assembly of the transformer cover.

The restoring was successful, now everything works perfectly.

In the picture you can see the last phase of the restoration, the calibrations.
