> "Where do you buy stuff for beverage like 470 ohm non carb resistor for terminating and cores for 9:1 in US ?"
Ohmite and IRC/TT still manufacture non-L, carbon composition resistors. If there's a reason to avoid carbon composition, Ohmite and KOA manufactures ceramic composition resistors in their OX (1-watt)/OY (2-watt) product line. In the U.S., these resistors are available from Mouser, Digikey, Newark/Element 14, Allied, and Arrow Express. Regarding toroid cores, W0BTU has assembled a nice compendium of data on the subject.
