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. It features the same basic display characteristic of a single shadow that opens or closes according to the supplied input voltage. The tube requires a relatively low target voltage of only 180V (opposed to the 250V typical for most magic eyes), the closely related 6ME10 even just 100V.
Not many devices seem to have used this tube. One example is the Heathkit GR-21 radio.
