Good idea. I just bought the Sams Photofact for this chassis which has some useful info. For example it says if the AGC delay control is set properly, the signal at output of the detector should be 3.5 VPP during normal operation.
I'll start by going through the voltage and resistance chart for the tuner and IF first though.
I'm also curious about the 470pF cap that couples the output of the tuner to the IF.
