Seems everything is working. I got rid of the whistles when approaching a station by slightly detuning the IF trimmers. Not sure what is happening there, some sort of hetrodyning. Component layout and wire layout is about the same as original. Perhaps still something with the oscillator coil. I even confirmed that the osc. frequency is above the tuned frequency.
Sitting on the bench with her older sister, the 70. I like the style of the 70 better. The 70 is original finish, the 71 was already refinished when I bought it at the auction. Quite a nice job. The 71 definitely sounds better. Less distortion.
