[Amps] stability of amps

[Peter Chadwick]

I suspect the real question is:
Does anyone have the s (or y or z) parameterts of the 572B at frequencies up to 50 MHz and beyond? This would tell you the potential stability.
My experience with 572Bs  is that they are a real wotsit at 10 metres anyway, and personally,. I'd avoid them like the plague
Obviously, Carl can tame them on 6. He's a a braver man (or some would say, a better engineer) than I am to attempt it!!!. What sort of efficency do you get, Carl?

How does the instability show - what frequency is any oscillation at?
