Without getting into (God help me) the controversial Measures theory, it is a
fact that carbon resistors in parasitic suppressors, such as are used in
Heathkits, are prone to rise in value with heat and time.  They can also open as
a result of excessive heating, common when these amps are used on 11 meter am!

Therefore, it's worthwhile to make sure the resistors are in good shape, and
replace them if needed.  Measures recommends metal-oxide resistors which deal
with the heat much more gracefully.
