The Kook is talking about audio power amplifiers oscillating because of accidental POSITIVE feedback - ie capacitive coupling from the output to a non-inverting input. Each case if different, but something like a 50 to 100pF cap from the speaker out to the non-inverting input will send almost ANY tube or transistor power amp into full power oscillation.

Why did such heavy oscillation occurred within my amplifier circuit when there was no AC coupling capacitor between voltage amplification stage (MC1458) and output power stage (upper and lower Sziklai pair with paralleled power transistors)? By the way, C3, C4, C5 and C6 represent AC bypass to avoid distortion when AC is applied to such circuit.

The amplifier was running at less than 2 volts below the maximum rating. To rule out the possibility that the opamp itself becomes unstable I dropped in a OPA551 which works up to +/-30V. It still shows the exact same problem. I also run the NE5534 version from a lab power supply at +/-12V and it showed similar oscillations.

OSCILLATION The normal power supply decoupling precautions should be taken when installing the LM380. If VS is more than 2× to 3× from the power supply filter capacitor it should be decou-pled with a 0.1 mF disc ceramic capacitor at the VS terminal of the IC.
