- Even though the load impedance is lower, relatively speaking?

Well if you read the operating specs for 6550 as tetrodes, 440v for Ea,
and lower V fpr Eg2, they get thd down to 0.6% at 40 watts, I have forgot
the exact figures, but the secret is the low Eg2 relative to the anode
supply, once that supply is over +300v.

I meant, you use say a 5k load for class AB1, it needs to be lower, maybe
3 or 4k, to accomidate the higher peak current and power in AB2. But what
happens to the distortion level when it's still within A or AB1?
