I considered that briefly, when repairing a vertical problem on the same model Philco... I could not find any 7N7s in my tube stash, but have many 6SN7s ... turns out they are easily found on eBay, and seem to be cheaper than 6SN7s. Several sellers seem to be selling converter sockets so that 7N7s can be used to replace 6SN7s... rather than the other way around. Perhaps the "tube amp" folks are really sucking up the supply of 6SN7s.
However, It took a new 6S4 (also from eBay) and a couple of caps to restore full height.
