I'm a bit of a primitive guy so I would connect an outdoor antenna to the Philco and loose couple the output of the RF amp (grid cap of the 6A7) to the antenna post of a BC set. This can be accomplished by a  a small cap (100pf or so or 2 pieces of hookup wire twisted together a bunch of times). Tune both sets to a station on the same frequency and see if the station as you tune the Philco.
By connecting the generator and scope to the coil it may detune it from added capacity from each device.
