Are you saying skip using the VSM method to get an overall response curve? All the books Im reading is saying use the VSM to get an overall response curve from the tuner to the output of the bandpass amp. even sencores method is this way. well, i wasnt going to tweak anything in the IF section, but the fact I cant get a response curve at all is something I want to figure out. Something wrong with the tv, or something wrong with my gear, or my set up? I did manage to get a curve when direct injected into the bandpass amp, as per Step 1 of the Rca service manual. But following the rest of the instructions gives me nothing. I hope i didnt short and burn something out when connecting up the bias voltages.
