I wouldn't use a resistor for a rf filter.
A choke will do a much better job. For now I'd leave 47 @ 8mf see what happens depending on what it's trying to do. It's either stopping noise from other circuits from getting into the osc or signals from the osc getting out of the osc. Common practice now days would be to use a small value cap across 47 like a .01 or .005. This most of the time will block the signals from getting out. The choke and large cap stops low frequency (audio,hum, and such) from getting in.
When you get it working and it doesn't want to settle down squealing and behaving badly add some more mfd's there.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
