*Barely visible at the top right is the black on/off switch. If you have a vivid imagination, you can see the "Aus" on the left for "off," and you can see the "Ein" on the right for "on."
*The two white objects are porcelain fuses and holders.
*"Taste" = key = connection for the Morse Code key
*The clear eye at the top-left is the control lamp for the power supply.
