given the new discoveries reported here, I tried.
2204, Vega at half TX sensitivity, guitar volume 8 at all times;
Amp settings were presence 0, bass 0, mid, treble 5, master 6 preamp 6
U47 close up; EQ in post was flat except for bass removal and a hole around the five hundred hz; used plexi baffles to obtain boxy sound plus closed reverb.
UPDATE: Our friend and member Currentpeak has just found this superb interview in audio form where Powerage sound engineer Opitz describes how Angus recorded the album back then.
This is Currentpeak‘s understanding, I am posting his comment as a whole:
It is a Michael Butler’s (of Rock ‘n’ Roll Geek Show) interview with Mark Opitz. As we know, he was an audio engineer/mixer/producer for many Albert Productions’ artists including AC/DC, The Angels, Rose Tattoo = real rock royalty! (more…)
