What Mauri says is true, Rich for some reason always overlooks
that point.
The suppressor impedance required varies with layout, and can
range from no suppressor at all to a suppressor with very high
parallel impedance.
Claiming one suppressor technique is a cure for all systems is silly.
For example, adding Rich's hairpin suppressor to the AL-80B
actually increases VHF anode system Q.
