Very nice video about a very obscure thermatron. I did not know the EF50 history or purpose even though I have a couple. A nice piece of thermatron history (I could not find anything about it in Tube Lore).
ReplyDeleteA very detailed history of the EF50 and British TV and radar is at: https://www.dos4ever.com/EF50/EF50.html
