Framed Letter Signed by Audion Tube Inventor LEE DEFOREST
Here for your consideration is an Exceptional 20” x 16”Framed Letter Signed by Lee de Forest while he was Director of UNITEDENGINEERING LABORATORY.
Lee de Forest invented the Audion-the first vacuum tube thatcould take a weak electrical signal and amplify it into a larger one.
From the NET:
Lee De Forest invented the audion, a vacuum tube device thatcould take a weak electrical signal and amplify it into a larger one. Theaudion helped AT&Tset up coast-to-coast phone service,and it was also used in everything from radios totelevisions to the first computers. The audion, or triode, at the heartof the vacuum tube is what the transistor was built to replace.
De Forest was born in Alabama to a Congregational ministerwho hoped that his son would continue in his footsteps. Instead, DeForest went on in physics, getting his Ph.D. from Yale in 1896. He begantinkering and inventing things even in high school, often trying to buildthings that he could sell for money. By the time he died he had over 300patents, but few of them ever met with much success.
In fact, De Forest seems almost to have had a nose forfailure. He was regularly involved in patent lawsuits (indeed, he spenthis fortune on legal bills). He went through four marriages, had a number offailed companies, was defrauded by his business partners, and was even onceindicted (but later acquitted) for mail fraud.
With the audion, however, De Forest had a solidsuccess.De Forest has been labeled one of the fathers of the"electronic age," since the audion helped start the explosion ofelectronics earlier this century. De Forest invented the device in 1906,by inserting a grid into the center of a vacuum tube. Applying voltage to thegrid controlled the amount of a second current flowing across the tube.In 1913, AT&Tinstalled audions to boost voice signalsas theycrossed the US continent. Soon the audion was being used in radios aswell.
In 1921, De Forest invented a way of recording sound onmovies. He started a company, the De Forest Phonofilm Corporation, but hecouldn't convince the film industry to try using sound. Once film makersfinally came around, several years after the Phonofilm Company folded, theydecided to use an entirely different method. (Though some time latermovies actually began to use the method De Forest originally proposed.)

I was the President of the New England Antique Radio Club and then the New England Vintage Electronics Club for six years. I stepped down at the end of 2018 to concentrate on finding new owners for the Vintage Electronics my son is not interested in.

If you don't know how to hook up or use what you are buying, or know someone who does, please don't buy.

5) Shipping is expensive.
You can pick your item up with NO SHIPPING costs at my home 50 miles north of Boston with advanced notice.
The concept of "free shipping" is one of the 3 biggest lies.
We are the best packers on , and pack YOUR item the way we'd like to receive it-if it was being sent to us.
We take extra care in packaging, (Bubble wrap, foam pellets, proper boxes, etc.)(NOT the wadded up newspaper trick) There is a cost for doing this right.
Our goal is to get it to you in good shape, and for you to not have to file those fruitless shipping claims.
Let's face it, once it's broke, it's broke.
We have lost a significant amount of money in packaging costs over the past 25 years, and will continue to do so to get it to you in one piece.
6) YOU & US: Note that the majority of what we sell is antique, vintage, and/or collectable electronics.
For liability purposes, Radioorphanage / Bruce Phillips accept NO responsibility for how the buyer uses or misuse of the items.
We see you as a valued customer, and want you to be happy.
Buy with confidence, as we are in this for the long haul- not for a quick buck.
If you are not happy, for any reason, let us know and we'll try to make it right.
