resistor in lm384 datasheet?

hi
there is a resistor on the data sheet for the lm384 that says 2.7 is this 2.7ohms or 2.7kohms.
and can anybody see a problem with using a 470uF cap in the place of the 500uF one. and a 4.7uF in the place of the 5uF as i have some of these allreddy.

No problems. That's called a "Zobel network" and keeps the amp out of trouble with inductive loads at HF or if the load is disconnected.

oh
but is it a 2.7k or 2.7ohm
or is it something compleatly different and not a resistor at all

2.7 ohms.

thanks

why is it so hard to find 2.7ohm resistors
what do u recon will happen if i use a 2.2ohm one?
