Same tube, except that the 6L6G has a slightly higher output I think, but it probably won't matter, yes watch for pin one being used for things other then a ground, Philco liked to do things like that to punish people for daring to use metal tubes from the evil RCA. I'm surprised that your set doesn't have something goofy like a pair of 6B4Gs, which was the octal version of a 6A3.
