The world's smallest Vacuum tube TV bar generator ?

Well , maybe not the smallest , but I've never seen one smaller . This uses 1 tube , a 12AT7 , and a selenium rectifier with an assortment of the usual resistors , caps , and coils . I haven't yet tried it , but I can't imagine it being all that useful next to my 1077B .
