Terry...so if I understand you correctly, I should try putting a 100pF cap between the plate of the 1L5N IF tube and the diode plate (DP on the schematic) of the 1LD5 Det.-Amp tube (essentially by-passing the 2nd IF transformer). Then try the signal generator again...right? see...chemists can learn this stuff too...
...and not getting any older does have its down side as well....
