Replication of Dr Stifflers SEC Circuit ( Demo )

may not be feedback ... rather it could be just a carrier wave in the am band. The oscillator likely emits radio waves on various harmonic frequencies.

Feedback could be acoustic disturbance of assembly or due to emf from driver coil.

Nice setup,

try a litz coil or a hand wound 10 to 50 turn coil directly before the Avramenko plug and put it addiotionally onto the core. This will even light up the LEDs still much brighter with less input current.

Many thanks.

Excellent job! Nice work on discovering the feedback phenomenon. I like your use of the low tech am radio approach which allowed you to hear something others had not, and now might lead to who knows what?
