Hi Rag

Here is a good source for the correct 470 ohm resistor.

Hi Rag,

the important is to look for carbon composition / ceramic composition
resistors
at 2W power rating at least. The Ohmite has their OY series / 2W for
example.

"Metal" or "Ceramic" composition resistor. Maybe Farnell would be ok place
to buy from in Europe?

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.  In particular, see the postscript written by Barry, N1EU:

Re: Topband: 470 non carbon resistor

[Mike Waters]

Those are likely Ohmite type OY 2 watt ceramic/metal composition resistors.
They are non-inductive and are the preferred choice for Beverage
terminations. They will survive higher surge currents from nearby lightning
strikes than carbon composition.

http://www.ohmite.com/catalog/pdf/ox_oy_series.pdf
Mouser Electronics # 588-OY-470-E

The cores are Fair-Rite # 2873000202 (Amidon BN-73-202). Newark/Farnell has
them, I believe.

[william radice]

 A carbon resistor is what you need, NOT a non-carbon.
You can get them here...among other places. Not real hard to find
