I had a reader enquiring about substitutions for the rogers 6X6 eye tube. This tube is commonly found in Canadian Rogers or Deforest crosley radios.
It would be good to know more about which tubes are valid subs , or details about re-basing or modifying the radio circut to accept more common eye tubes. If you have info on this , please respond to this thread.
I did find a good link to a page that talks about eye tube subs. that link is here
The 6X6 is indeed a rare tube and goes for a pretty penny when available. The pattern is similar to the 6AF6/6AD6 tube with left and right openings and the pin-out/tech info is shown on the attached figures. This info may be useful if making a substitution. A (much more common and cheaper) 1629 will work but has a 12v heater and a voltage doubler circuit is needed – a suitable one is described in the Radio Wrinkles article at https://www.antiqueradio.org/magiceye.htm.

The following page has photos and animations of many eye tubes ‘in action’: https://www.akh.se/tubes/eyes.htm. Several 1629’s are usually for sale on Ebay.
