If stages are often peaked. For ham use, it should be acceptable. One
particular problem may be that am stations will not have full bandwidth, so
the audio may be restricted a bit. If you are careful, you can emulate the
sweep generator by setting the generaator above, on and below the if
frequency. The total bandwidth should be the desired wide bandwidth. Then,
adjust the transformers so that signal level is about the same on all three
frequencies.

A few years ago, I acquired a spectrum analyzer with tracking generator.
Now, alignment of any filters or if stages are so easy that I feel guilty.

I also recall using a BC-221 as a manual sweep generator.

the improtant thing is that you will come close with the old "peak each
stage" approach. Make sure you do not overload and follow the other
instructions. I have aligned more than one receiver by ear, when I had
nothing else. Generally, close is good enough.

Also, make sure you use the proper alignment tools. I have worked on a lot
of receivers butchered by improper alignment tools.
