You should be getting the same volume when injecting a signal at point A and B. If it's a quiet tone then you may have a weak 6V6, but at least you know the audio works and can come back to it later.
You will always need an antenna to receive signals, especially FM. Use a loop of wire attached to the antenna terminal. Concentrate on the AM section first. It would be nice to be able to inject a 455 kHz IF signal at the antenna and different points in the RF stages. Barring that, maybe there's a trouble shooting section in your documents for this. Also, check the tube voltages and compare them to the voltage chart. It may give you a starting point.
