With the tape running is the ONLY way to adjust azimuth; I can't imagine doing it any other way.
Unless you have an accurate test tape with an alignment tone, using an oscillograph isn't going to help much. The most effective method will be by ear - possibly "borrow" a teenager who can still hear upwards of 15khz.
The left/right balance on cassette tape is never reliable or stable - the tolerances of the format are just too imprecise, and auto-reverse transports are almost always much worse than single direction machines.
Loudness (recording level) and good HF response are inversely related; if you want good HF response you have to lower the recording level; you'll notice the frequency response of cassette decks is always quoted at levels of something like -20dB, so they can achieve values up to 20khz.
