Default simple(?) question...

What do you do for resistors if you can't get carbon composition in the
ratings you need? I built a MFJ-1020A out of surplus and scrap before


I can't imagine that the resistors have enough inductance to
make any difference at HF. Plus, the reactive component
is in series with the resistance, which would increase the
impedance of the resistance slightly--in most cases that
would be more of a benefit than a hinderance; since I'd
bet most of the resistors are being used for biasing active
components, or to provide signal isolation..

Does anyone have any evidence that it makes a hill of
beans difference at HF?
