[R-390] 47 Ohm resistors

Hi

Even these days the "nominal" line voltage in different parts of the 
country varies by a lot more than 1%. Unless we want to get out to 
three digit readings on AC wall sockets anything in the 42 to 56  ohm 
range seems to work ok. I have seen radios with values both above and 
below that range running along just fine. If 50 ohms is what you have 
then I'd go with it.

A 50 ohm resistor should dissipate about 3 watts in the application. A 
five watt part will do ok.

	Take Care!
