All right. You folks insisted...so I took some time a little after 7pm EDT this evening, moved my RCA T8-14 chassis out of the way, and tried out the Philco 70 chassis on my longwire antenna.
Here are the results as I slowly tune from the high end of the band to the low end:

Notice how it begins to get quieter as I go below 1000 kc, which indicates that bending plates did no good. You will also notice that it picks up a station broadcasting at 760 kc at 70 on the dial. So the alignment is definitely off and needs to be redone.
Right now my RCA T8-14 has priority, so nothing more will be done to this 70 until the T8-14 is finished. I have a used B+K 4040 signal generator on its way here and if it turns out to be OK, I'll use it to realign the 70.
I think that if nothing else, this video clearly shows that it is past time to retire that old Clough-Brengle signal generator I have been using.
