RE: the pin 1 / 2 connection

This maybe the source of your problem.
Pin 2 is the input grid or G1 . Pin 1 in the early el84 was IC or internally connected. Some, especially, currently made el84 have p1 unconnected in which case it makes it an ideal tie point for the grid stop resistor on the tube socket. I don't know why one would intentionally tie those 2 points together.
I believe the vintage Sylvania have the P1 design IC, in which case the input signal to the tube is not going to the signal grid if in your amp the P1 is used for the grid stop resistor.
