When I aligned the sound IF I did as you said and turned tuner to blank position like the instructions say to do in the manual. When I hooked convertor box to mixer grid I then set the tuner to channel 3. Wouldn't this enable the local osc? You gave some great ideas for testing video IF. My signal generator I got should be able to do this no problem. I discovered though it is quite limited for sweeping functions. I disabled all the high voltage and removed the crt for what I am doing right now so I will try that later when I reconnect everything. I did verify my signal generator accuracy by using my Sony multiband radio using the SW band and tuning in to generator.
