Tom's Radiocollection - TRC-6005
As young, fresh educated, Radio-officer - "SPARK" -
I sailed to New York - U.S.A several times on my first ship
"Dyvi Oceanic"
1973 - 1974
I always took a trip into the Big City - NEW YORK -
and was of course highly amazed
over what The Electronic Shops had to offer in this great town!
Walls up and down filled with great stereo - amplifiers!
My dream was to buy a SANSUI - and after 8 months sailing I bought:
"My First Sansui - The Great AU - 555 A"
