Well, similar but different.
My last duty station was aboard CA-148, USS Newport News, a Des Moines class heavy cruiser. I started out making coffee for the Fox Div sailors in the port side amplidyne room, aft. My shipmates soon realized I had no coffee making skills so, they turned me loose on the MK 56 RADAR systems. A well tuned MK 56 RADAR could track and lock on to seagulls. The MK 56 RADAR was all vacuum tubes. In preparation for my first Captain's Inspection, I removed all the vacuum tubes in the system (there were dozens of them) and washed them all. The 1st class FT I reported to almost fainted when I showed him my work and how I had gotten the system looking so clean. He said, the RADAR will likely never work again. Little did he know, I had worked with vacuum tubes for years before joining the USN. Also, my USN father had developed some of the USA's first RADARS during WWII (The US had no operational shipboard RADAR when we entered the war). My Battle Station was the MK1 Fire Control Computer, aft.
