>But what amazes me is the number of amateur amps (both HB and commercial) 
>that don't even *have* an RF-tight output compartment! The
power supply, control wiring, mains wiring and even the RF input circuit are 
all swimming in RF. And then we wonder where instabilities come
from...<

I have long since been of the opinion that the most important item of 
equipment in the amplifier builder's toolbox is Occam's Razor.
