Ok. I changed out these tubes, one at a time, and still got no signal back in from the generator in the RF alignment of 1600, 580, 1600 and 1500 instead of the buzz.
6A8G
6N7G
6K7G
HOWEVER: I did discover that the IF signal of 470kc does play up and down the dial. It begins to fade around 1200 on the dial, but is still present up to 1600. But, that does me little good since i can't perform the RF alignment getting nothing but a harsh buzz instead of a smooth signal tone. I can hear the occasional station, but it's scratchy and may as well be lost in space as far as where it's supposed to be on the dial.
