[Amps] drive power

[Bert Almemo]

Hi Tom,

What you're saying makes sense. I have an IC-746 driving an IC-2KL and that
amp needs about 35-40 watts drive. I'm reducing the drive but maybe that's
not the way to go. Any ideas?

If an amp requires very low drive and is driven by a 100 watt exciter, it is
a very poor system.

Sometimes people think it improves distortion, but it often does just the
opposite.
