[R-390] More on shared resistors

[w9ya at arrl.net]

Hey Perry;

I may misunderstand your needs but I looked at the resistor kits that
Digikey offers.

Digikey sells 5% carbon film 1/2 watt resistor kits. There are three such
kits, two of which should cover 90% of your needs as per what you indicate
below. (As I read it.) Each of these two kits is under 17 bucks, or 34
bucks total. A few extra resistors should bring the total up to 50 bucks
or so per unit.

Not so bad.

Oh yeah the Digikey part nos. are RS150-ND and RS250-ND .
