How good are your ears at 1MHz ?

Afraid I can't hear 1MHz. But I have heard - and measured - a change in
amplifier performance in cases where the amp has been producing bursts of
oscillations at such frequencies with loads it did not like at RF.

As before, I am quite surprised that someone who I thought had designed and
tested amp may not have encountered this.

Slainte,
