Audion Amplifier
De Forest Radio Telephone & Telegraph Co.
New York City

These pictures show two original 3 1/2 volt tungsten filament Audion Amplifiers.  One is complete with the original tag and seal that is to be removed when it is FIRST put in service.  This tube has never been used and is complete with its original box and cotton packing material.  The tube to the left of the box in the right picture may have been used but the filament checks good.   I have its box and original packing material but the box has seperated at its seams and needs a bit of help.  These tubes and boxes are so old I have not removed the NOS tube from its box in over 25 years.  I only removed it to take the pictures and then carefully returned it to its place in the display cabinet atop my Grebe CR-18.   Perhaps I'll take it out of the box again in 2024.
