SO A LITTLE CHARACTER LIKE YOU IS GOIN6 TO CHANGE THE ENTIRE ELECTRONICS INDUSTRY~
THAT'S RIGHT! LOOK WHAT
I'M DOIN6 FOR. PORTABLE RADIOS. MY GENERAL ELECTRIC ALL - TRANSISTOR SET 15 SMALL. LIGHT, COMPACT. WHY, IT CAN BE CARRIED IN A POCKET".
ANYWHERE,!
L.ISTEN TO THE PILOT. HE KNOWS ALL ABOUT ME.
WHY, WHEN I'M FLYING, THE LIVES OF MY PASSENGERS AND CREW DEPEND ON THAT STURDY LITTLE FELL.OW.

TOWER, I READ YOU LOUD AND CLEAR. WE'RE PREPARING TO LAND'A~E!f&i
WELL - TRANSISTORS ARE SOLID DEVICES, UNL.IKE VACUUM TUBES. A REMARKABL.E METAL CALLED GERMANIUM DOES THE JOB . THE TRANSISTOR AMPLIFIES CURRENT BY ADDING Et.,ECTRON5 AS ELE'CTRICITY FLOWS' THROUGH' ITS GERMANiuM CRYSTAL. THERE . ARE NO FILAMENTS TO BURN OUT, NO GLASS TO BREAK. '
THE BATTERY IN THE GENERAL ELECTRIC ALL- TRANSISTOR SET STARTS ELECTRONS MOVING THROUGH MINUTE OPENINGS IN THE GERMANIUM . .. THEY PICK UP MORE ELECTRONS AS THEY GO ALONG. THIS PROVIDES THE POWER TO MAKE THE RADIO PLAY •
TRANSISTORS HAVE ONLY BEEN AROUND A FEW YEARS, RIGHT ~
~16HT YOU ARE. THEY WERE FIRST PROVED PRACTICAL FOR TRANSMITTING ELECTRIC SIGNALS IN 1948. SINCE THEN THEY'VE DEVELOPED FAST.
"EVERY POSSIBLE TEST WAS TRIEO TO OESTROY THEM. H IT'LL BE A MIRACLE IF THE TRANSISTORS WORK AFTER BEING SHOT FROM A MORTAR. IT'S A FIC BLAST.
I READ ABOUT OTHER EXPERIMENTS THAT SHOW TRANSISTORS CAN BE OPERATED AT THE BOILING POINT . . . 212 DEGREES FAHRENHEIT, AND CAN BE STORED AT 275 DEGREE'S.
AND, DAD, BESIDES BEINGTINY AND LASTING 50 LONG, KNOW WHAT OTHER ADVANTAGES THERE ARE TO TRANSISTOR RADIOS:
BUT 00 YOU SUPPOSE TRANSISTOR RADIOS -r" GIVE AS GOOD TONE AND VOLUME AS THE LARGER ONES?
