Resistors for Predicta

[dtvmcdonald]

My comment on resistor types:

First, I always try to replace carbon comp resistors with modern film ones
that are the same physical size, not smaller. Modern film ones always smaller for the same rated wattage , which means at rated power they will get hotter: not good!
And this looks more authentic, even if they are bright blue.

Second ... some modern film types in fact have spirals of resistor element.
This won't cause a problem at audio or NTSC video frequencies ....
but most certainly can and will in VHF/UHF tuners. At 41 MHz IF frequencies,
I have no experience so can't make a statement.
