This was a dozen years ago for the GM70 amp I took to NY Noize. A choke approximates a current source and when you put two current sources in series they fight each other. I suspect the CCS was winning but the choke has that "inductive kick" that the regulator then corrected for.
I think the amorphous core was key because it has lower losses at high frequency and since this was happening at 70Khz the core may still be in the picture.
