 My guesstimate: a loaded Q of about 10.

 When doing what I call a reverse SWR check,

Where you place resistors from the plate connection to ground to 
simulate the Plate Load Impedance.

Then activate the T/R Relay.

And measure the SWR on the amp output.

What is the typical say 1.5 to 1 SWR bandwidth on the various bands?

I would assume on 80 is it far smaller than on 10.

But what is typical for a typical Amp like a Heath SB-220?
