Just spotted the closed thread on UKVRR site from 1910, I must have missed it as I can't remember it. .... I've got my late Mothers Elizabethan T12 B/W single standard portable she got free in 1971/72 that still works, the brightness/ black level was/still is all over the place so presume it has AC coupling..
