The 6ME5 (also known as 6M-E5) is a miniature magic eye tube manufactured by TOYO in Japan. It closely resembles the common 6E5 tube, but in a smaller form factor, featuring the same basic display characteristic of a single shadow that opens or closes according to the applied input voltage. The tube operates at a relatively low target voltage of 180V, while a similar variant, the 6ME10, works at an even lower target voltage of just 100V.
Although it was used in certain radios, such as the Heathkit GR-21, the 6ME5 remains a rare and unusual tube.
