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:
