It could be possible, not very likely, the 6AL5 may have been replaced, socket and tube, with a 6H6. I have seen some weird 6H6G tubes.
On the tube in question, does it have two 100K ohm resistors connected to the socket?

The horiz out is a 6BQ6, osc 6SN7 and a 6H6 phase det.
I saw one that had a 6H6 Canadian Rogers spray shield GT type glass tube. It had a large orange "M" stamped on the base.
The claim was, there was a shortage of tubes and electronic parts for a while, during the Korean war. That's why you see a lot of foreign parts in some of the sets of the day, especially Admirals.
