ZENITH HEARING AID

HERE IT IS FOLKS. THIS IS A HEARING AID MADE BY ZENITH IN 1941. IT IS AC POWERED AND USES 3 TUBES. AN '84' RECTIFIER, A '41' POWER AMPLIFIER AND A '79' WHICH I AM NOT SURE ABOUT BUT PROBABLY IS AN AUDIO FREQUENCY AMPLIFIER.
IT WAS PLACED ON A TABLE AND PLUGGED IN TO AN OUTLET. THE UNIT PICKED UP THE SOUND FROM A PERSON OR OTHER SOURCE SUCH AS A RADIO OR PHONOGRAPH, AMPLIFIED IT AND THE USER HEARD IT THROUGH THE EARPHONES.
I WILL SHOW SEVERAL VIEWS AS WELL AS THE ORIGINAL INVOICE AND INSTRUCTION BOOKLET. AS YOU CAN SEE, I ALSO HAVE THE ORIGINAL BOX. BTW, THE EARPHONES SHOWN ARE THE ONES THAT CAME WITH THE UNIT AND ARE MADE BY 'BRUSH'. I NEVER HEARD OF THAT BRAND.

THE KNOB ON THE SIDE ADJUSTS THE VOLUME
THIS KNOB HAS THE ZENITH "Z" ON IT
AND THE KNOB ON THE UPPER REAR
IS USED TO ADJUST THE FREQUENCY
THIS COMPENSATES FOR RESPONSE TO VOICE, MUSIC ETC.

 
 

 
 

 
 

 
 

I THINK THIS IS NEAT. IT IS A HEARING AID MADE BY ZENITH, I EVEN HAVE THE ORIGINAL SALES SLIP FOR IT.
