Unknown tube in Philco 48-482
#2

The 7B6 is the loctal equivalent of the octal 6SQ7GT. They are both twin diode hi-mu triodes.
The pin out is different also. Does it look like the socket was replaced and rewired or original?
The schematic does show the 6SQ7GT. This chassis does employ a lot of the 7 series tubes. Possible that Philco ran out of 6SQ7GT's and/or decided to use up their stock of 7B6's?
More than likely it was changed out at some point by someone who did not have a 6SQ7GT around!
The radio should work well with either.
